(un)?register_netdevice_notifier_dev_net() hold RTNL before triggering the notifier for all netdev in the netns. Let's convert the RTNL to rtnl_net_lock(). Note that move_netdevice_notifiers_dev_net() is assumed to be (but not yet) protected by per-netns RTNL of both src and dst netns; we need to convert wireless and hyperv drivers that call dev_change_net_namespace().
