[SCSI] scsi_debug: fix false positive logical block reference tag check fail

Reading partially unwritten sectors generates a false positive logical
block reference tag check failure when DIF is enabled.

This bug is caused by missing ei_lba increment in loop of dif_verify()
when unwritten sector is skipped.
