    Fix interface add for dvr with gateway

    when an interface is added after router gateway set, external
    connectivity using snat fails. Instead of just adding the snat port for
    the new subnet, method internal_network_added(..) incorrectly re-adds
    all the snat ports with wrong cidr.
