Ming Lei 81ea1222f2 Revert "block: Merge bio before checking ->cached_rq" 
This reverts commit 23f3e3272e.

blk-mq sched bio merge still needs request to grab queue usage counter,
so we can't simply call blk_mq_attempt_bio_merge() when queue usage
counter isn't held.

Fixes: 23f3e3272e ("block: Merge bio before checking ->cached_rq")
