netdev: Make netdev_create_from_genl, netdev_destroy public

Make netdev_create_from_genl public and change signature to return the
created netdev or NULL.  Also add netdev_destroy that destroys and
unregisters the created netdevs.  Both will be used to move the
whole interface management to a new file.
