Fengnan Chang 4d0e1f2139 blk-mq: use queue_hctx in blk_mq_map_queue_type ...

Some caller of blk_mq_map_queue_type now didn't grab
'q_usage_counter', such as blk_mq_cpu_mapped_to_hctx, so we need
protect 'queue_hw_ctx' through rcu.

Also checked all other functions, no more missed cases.

Fixes: 89e1fb7ceffd ("blk-mq: fix potential uaf for 'queue_hw_ctx'")
