Bluetooth: Fix debugfs entry leak in hci_register_dev()
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.
