rtnetlink: Add ASSERT_RTNL_NET() placeholder for netdev notifier. The global and per-netns netdev notifier depend on RTNL, and its dependency is not so clear due to nested calls. Let's add a placeholder to place ASSERT_RTNL_NET() for each event.

dev: Hold rtnl_net_lock() for dev_ifsioc(). Basically, dev_ifsioc() operates on the passed single netns (except for netdev notifier chains with lower/upper devices for which we will need more changes). Let's hold rtnl_net_lock() for dev_ifsioc(). Now that NETDEV_CHANGENAME is always triggered under rtnl_net_lock() of the device's netns.
