Aaron Thompson 63d6a3b078 Bluetooth: Remove debugfs directory on module init failure 
commit 1db4564f101b47188c1b71696bd342ef09172b22 upstream.

If bt_init() fails, the debugfs directory currently is not removed. If
the module is loaded again after that, the debugfs directory is not set
up properly due to the existing directory.
