NETDEV_UNREGISTER_BATCH seems unused we can probably remove it.
Indeed, the routing cache was the final real user.
I am tracking a device refcount issue, delaying net device dismantle by
1 second in netdev_wait_allrefs()
I guess we need to add a notifier called _after_ the final
synchronize_net() in rollback_registered_many()
