blk-mq: remove RQF_MQ_INFLIGHT
Since the previous patch change to only account active requests when
we really allocate the driver tag, the RQF_MQ_INFLIGHT can be removed
and no double account problem.
1. none elevator: flush request will use the first pending request's
driver tag, won't double account.
2. other elevator: flush request will be accounted when allocate driver
tag when issue, and will be unaccounted when it put the driver tag.
