scsi: return correct blkprep status code in case scsi_init_io() fails.
When instrumenting the SCSI layer to run into the
!blk_rq_nr_phys_segments(rq) case the following warning emitted from the
block layer:
blk_peek_request: bad return=-22
This happens because since commit fd3fc0b4d730 ("scsi: don't BUG_ON()
empty DMA transfers") we return the wrong error value from
scsi_prep_fn() back to the block layer.
[mkp: silenced checkpatch]
