Haotian Zhang 44aedcb251 media: cec: Fix debugfs leak on bus_register() failure 
commit c43bcd2b2a upstream.

In cec_devnode_init(), the debugfs directory created with
debugfs_create_dir() is not removed if bus_register() fails.
This leaves a stale "cec" entry in debugfs and prevents
proper module reloading.

Fix this by removing the debugfs directory in the error path.

Fixes: a56960e8b4 ("[media] cec: add HDMI CEC framework (core)")
