net: introduce NETDEV_POST_INIT notifier
For various purposes including a wireless extensions bugfix, we need to hook into the netdev creation before before netdev_register_kobject(). This will also ease doing the dev type assignment that Marcel was working on for cfg80211 drivers w/o touching them all.
