    Don't override device_owner for tenant network ports

    When a vif is passed to us from nova as a tenant port we shouldn't
    change the device_owner or device_id because that is what links the port
    to the nova instance. This enables the neutron nova notifier to trigger
    the correct events in nova for when the neutron port changes, e.g. being
    deleted, triggers the detach interface endpoint.
