Ming Lei 662156641b block: don't drain in-progress dispatch in blk_cleanup_queue() 
Now freeing hw queue resource is moved to hctx's release handler,
we don't need to worry about the race between blk_cleanup_queue and
run queue any more.

So don't drain in-progress dispatch in blk_cleanup_queue().

This is basically revert of c2856ae2f3 ("blk-mq: quiesce queue before
freeing queue").
