[SCSI] Redundant this_count check in sd_init_command()

I was going over the scsi I/O submit path, when sd_init_command
construct the scsi command, this_count is already checked in the
previous else if clause.  Why does it need to check it again in
the last else block?

Patch to delete the spurious check.
