We don't need to check for vlan_filtering being enabled every time we attach a port to the bridge, only on the first attachement of a port to the bridge.
We don't handle vlan_filtering state changes, so even if it was disabled later, we wouldn't be able to do anything about it. So let's only check the state once when populating cnetlink::bridge.
