Sven Eckelmann e44d8fe2b5 batman-adv: Disallow regular interface as mesh device ...

When trying to associate a net_device with another net_device which
already exists, batman-adv assumes that this interface is a fully
initialized batman mesh interface without checking it. The behaviour
when accessing data behind netdev_priv of a random net_device is
undefined and potentially dangerous.
