Ming Lei 3b87c6ea67 blk-mq: update hctx->nr_active in blk_mq_end_request_batch() ... In case of shared tags and none io sched, batched completion still may be run into, and hctx->nr_active is accounted when getting driver tag, so it has to be updated in blk_mq_end_request_batch(). Otherwise, hctx->nr_active may become same with queue depth, then hctx_may_queue() always return false, then io hang is caused. Fixes the issue by updating the counter in batched way.
