Ming Lei 52e1f85bf7 blk-mq: don't create hctx debugfs dir until q->debugfs_dir is created
[ Upstream commit f3ec5d11554778c24ac8915e847223ed71d104fc ]

blk_mq_debugfs_register_hctx() can be called by blk_mq_update_nr_hw_queues
when gendisk isn't added yet, such as nvme tcp.

Fixes the warning of 'debugfs: Directory 'hctx0' with parent '/' already present!'
which can be observed reliably when running blktests nvme/005.

Fixes: 6cfc0081b0 ("blk-mq: no need to check return value of debugfs_create functions")
