Yu Kuai 872e474f78 blk-mq-debugfs: add missing debugfs_mutex in blk_mq_debugfs_register_hctxs() ...

[ Upstream commit 9d20fd6ce1 ]

In blk_mq_update_nr_hw_queues(), debugfs_mutex is not held while
creating debugfs entries for hctxs. Hence add debugfs_mutex there,
it's safe because queue is not frozen.
