Otherwise, if netdev_unregister_provider() is called before any other
netdev function, netdev_class_mutex is not initialized and the attempt to
lock it aborts.
This doesn't fix an existing bug but with the following commit
--enable-dummy=system will make netdev_unregister_provider() the first
netdev function to be called.
