Bluetooth: Fix debugfs entry leak in hci_register_dev()
[ Upstream commit 5a4bb6a8e981d3d0d492aa38412ee80b21033177 ] Fault injection test report debugfs entry leak as follows: debugfs: Directory 'hci0' with parent 'bluetooth' already present! When register_pm_notifier() failed in hci_register_dev(), the debugfs create by debugfs_create_dir() do not removed in the error handing path. Add the remove debugfs code to fix it.
