trelay: handle netdevice events correctly

Browse Source 
Since v3.11, netdevice notification data are of type
"struct netdev_notifier_info". Handle it as such!

This should fix a critical bug in which devices are unable get released
because trelay does not release resources in response to UNREGISTER
event spamming the log with something like:

unregister_netdevice: waiting for eth0.1 to become free. Usage count = 1
