    fix network setup on evacuate

    As reported in bug #1430042 when using evacuate + neutron virtual
    machines fail to evacuate because of a failure to update port
    bindings. A similar issue applies to FloatingIP setup for
    nova-network.

    A related fix was proposed in
    https://answers.launchpad.net/ubuntu/+source/nova/+question/257358
    and seemed to be fixing users.

    This handles things a bit differently in order to more cleanly
    use existing code.
