ovs: fail OVS system interfaces when the db entry gets removed

Browse source 
If an OVS system interface that is active in NM gets removed
externally from the ovsdb, NM doesn't notice it and keeps the
connection active.

Let the OVS factory also handle the removal message for system
interfaces. In that case, we need to match the removed interface name
to the actual device, which can be of any kind.
