scsi: bsg: Drop needless assignment in scsi_bsg_sg_io_fn()

Commit e7def244f1b8 ("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.
