batman-adv: Keep batadv netdev when hardif disappears
Switch-like virtual interfaces like bridge or openvswitch don't destroy itself when all their attached netdevices dissappear. Instead they only remove the link to the unregistered device and keep working until they get removed manually.
This has the benefit that all configurations for this interfaces are kept and daemons reacting to rtnl events can just add new slave interfaces without going through the complete configuration of the switch-like netdevice.
Handling unregister events of client devices similar in batman-adv allows users to drop their current workaround of dummy netdevices attached to batman-adv soft-interfaces.
