Oops, it were suppose to read "+#include <scsi/scsi.h>". I thought it always
went to include/ if you used <...> (which then would had given an error). Oh
well, it compiles again when also adding "#include <scsi/scsi_device.h>" (used,
at least, in the scsi_cmnd-structure).

Since TRUE/FALSE are defined in "scsi.h", they were converted to the generic names.
Do this looks alright? Forgot it were dependent on the patch-set who converted
all "Scsi_Cmnd" to "struct scsi_cmnd".

Convert compatibility-glue-include "scsi.h" to <scsi/scsi.h> and friends.

Do not have the hardware, but since it compiles I hope it is alright.
