[NET]: Take RTNL when unregistering notifier
The netdev notifier call chain is currently unregistered without taking any locks outside the notifier system. Because the notifier system itself does not synchronise unregistration with respect to the calling of the chain, we as its user need to do our own locking. We are supposed to take the RTNL for all calls to netdev notifiers, so taking the RTNL should be sufficient to protect it. The registration path in dev.c already takes the RTNL so it's OK.
