block: mq-deadline: Track the dispatch position
Track the position (sector_t) of the most recently dispatched request instead of tracking a pointer to the next request to dispatch. This patch is the basis for patch "Handle requeued requests correctly". Without this patch it would be significantly more complicated to make sure that zoned writes are dispatched in LBA order per zone.
