net: Hold __rtnl_net_lock() in (un)?register_netdevice_notifier().
(un)?register_netdevice_notifier() hold pernet_ops_rwsem and RTNL,
iterate all netns, and trigger the notifier for all netdev.
Let's hold __rtnl_net_lock() before triggering the notifier.
Note that we will need protection for netdev_chain when RTNL is
removed. (e.g. blocking_notifier conversion [0] with a lockdep
annotation [1])
