net: lapbether: check register_netdevice_notifier() error in lapbeth_init_driver()
lapbeth_init_driver() ignores register_netdevice_notifier() errors and
always returns success, which can leave the module loaded without its
netdev notifier registered.
Check the error and remove the packet type on failure.
This is a future looking check, register_netdevice_notifier()
only fails on double registration or if the registered notifier
itself returns an error.
