block/mq-deadline: Fix a bug in deadline_from_pos()
A bug was introduced in deadline_from_pos() while implementing the
suggestion to use round_down() in the following code:
pos -= bdev_offset_from_zone_start(rq->q->disk->part0, pos);
This patch makes deadline_from_pos() use round_down() such that 'pos' is
rounded down.
