scsi: bsg: Drop needless assignment in scsi_bsg_sg_io_fn()
Commit ce70fd9a551a ("scsi: core: Remove the cmd field from struct
scsi_request") refactored scsi_bsg_sg_io_fn() so that it does not allocate
directly and hence does not return -ENOMEM in its error case. That makes a
remaining assignment of -ENOMEM to the return variable needless.
Drop this needless assignment in scsi_bsg_sg_io_fn().
No functional change. No change in resulting object code.

scsi: core: Remove the cmd field from struct scsi_request
Now that each scsi_request is backed by a scsi_cmnd, there is no need to
indirect the CDB storage. Change all submitters of SCSI passthrough
requests to store the CDB information directly in the scsi_cmnd, and while
doing so allocate the full 32 bytes that cover all Linux supported SCSI
hosts instead of requiring dynamic allocation for > 16 byte CDBs. On
64-bit systems this does not change the size of the scsi_cmnd at all, while
on 32-bit systems it slightly increases it for now, but that increase will
be made up by the removal of the remaining scsi_request fields.
