Conditional statements are faster than indirect calls. Use a structure
member to track the SCSI command submitter such that later patches can
call scsi_done(scmd) instead of scmd->scsi_done(scmd).
The asymmetric behavior that scsi_send_eh_cmnd() sets the submission
context to the SCSI error handler and that it does not restore the
submission context to the SCSI core is retained.

Since the removal of the legacy block layer there is only one completion
function left in the SCSI core, namely scsi_mq_done(). Rename it into
scsi_done(). Export that function to allow SCSI LLDs to call it directly.

The aacraid driver invokes scmd->scsi_done(scmd) for two types of SCSI
commands:
* SCSI commands initialized by the SCSI mid-layer.
* SCSI commands initialized by aac_probe_container().
The processing sequence for SCSI commands allocated by
aac_probe_container() is as follows:
aac_probe_container()
-> _aac_probe_container(scmd, aac_probe_container_callback1)
-> scmd->SCp.ptr = aac_probe_container_callback1
-> aac_fib_send(..., _aac_probe_container1, scmd)
-> fibptr->callback = _aac_probe_container1
-> fibptr->callback_data = scmd
fibptr->callback(scmd)
-> _aac_probe_container1(scmd, fibptr)
[ ... ]
-> _aac_probe_container2(scmd, fibptr)
-> Call scmd->SCp.ptr == aac_probe_container_callback1
-> scmd->device = NULL;
The processing sequence for SCSI commands allocated by the SCSI mid-layer
if _aac_probe_container() is called is as follows:
aac_queuecommand()
-> aac_scsi_cmd()
-> _aac_probe_container(scmd, aac_probe_container_callback2)
-> scmd->SCp.ptr = aac_probe_container_callback2
-> aac_fib_send(..., _aac_probe_container1, scmd)
fibptr->callback(scmd)
-> _aac_probe_container1(scmd, fibptr)
[ ... ]
-> _aac_probe_container2(scmd, fibptr)
-> Call scmd->SCp.ptr == aac_probe_container_callback2
Preserve the existing call sequences by calling scsi_done() for commands
submitted by the mid-layer or aac_probe_container_scsi_done() for commands
submitted by aac_probe_container().

Conditional statements are faster than indirect calls. Hence call
scsi_done() and reset_done() directly. The changes in this patch are as
follows:
- Remove the 'done' argument from aha152x_internal_queue().
- Change ptr->scsi_done(ptr) into aha152x_scsi_done(ptr).
- Inside aha152x_scsi_done(), check the 'resetting' flag of SCp.phase
since aha152x_internal_queue() specifies the 'reset_done' function
pointer if and only if the third argument has the value 'resetting'.

Introduce a structure with driver-private data per SCSI command. This data
structure will be used by the next patch to store a function pointer.

in struct scsi_cmnd. This patch prepares for removal of the scsi_done
member from struct scsi_cmnd.

Conditional statements are faster than indirect calls. Hence call
scsi_done() directly. Additionally, update a comment that refers to the
REQ_ATOM_COMPLETE flag since that flag has been removed a long time ago.

Conditional statements are faster than indirect calls. Hence call
scsi_done() directly.

Conditional statements are faster than indirect calls. Hence call
scsi_done() directly. Since this patch removes the last user of the
scsi_done member, also remove that data structure member.

The DEF_SCSI_QCMD() macro passes the addresses of the SCSI host lock and
also that of the scsi_done function to the queuecommand_lck() function
implementations. Remove the 'scsi_done' argument since its address is
now a constant and instead call 'scsi_done' directly from inside the
queuecommand_lck() functions.
