    network topology: handle port AZ correctly

    Previously d3 version of the network topology view handles ports with
    device_owner 'compute:nova' and 'compute:None' specially. This leads
    to the situtaion that neutron ports with non-default AZ are not shown
    properly. There is no reason to handle neutron ports with the default
    AZ differently. What we would like to do is just to classify neutron
    ports attached to nova servers.

    This commit changes the logic to check device_owner of ports have
    a prefix 'compute:'. Note that we also need to check if device_owner
    is a string before checking the prefix.
