v2->v1:
Follow Claudio's suggestions and the docker test result, Fix the dereferencing
'void *' pointer issues and the coding style issues.


In this current design, The GET LBA STATUS parameter data only contains
an eight-byte header + one LBA status descriptor.

How to test:
host:~ # qemu-system-x86_64 \
...
-drive file=/vm0/disk0.raw,format=raw,if=none,id=drive0,discard=unmap \
-device scsi-hd,id=scsi0,drive=drive0 \
...


guest:~ # dd if=/dev/zero of=/dev/sda bs=512 seek=1024 count=256

guest:~ # sg_unmap -l 1024 -n 32 /dev/sda

guest:~ # sg_get_lba_status /dev/sda -l 1024
No indication of the completion condition
RTP=0
descriptor LBA: 0x0000000000000400  blocks: 32  deallocated

Lin Ma (3):
  block: Add bdrv_co_get_lba_status
  block: Add GET LBA STATUS support
  scsi-disk: Add support for the GET LBA STATUS 16 command

The get lba status wrapper based on the bdrv_block_status. The following
patches will add GET LBA STATUS 16 support for scsi emulation layer.
