    Update internal snat port prefix for multiple IPv6 subnets

    In neutron when multiple IPv6 subnets on the same
    network are added to a router interface, the router
    interface port is updated with multiple fixed_ips rather
    than creating a new port. In the case of IPv4 subnets
    a new port is created for every added interface.

    For dvr routers there are internal snat ports that are
    created for every router interface that is added to a
    router. So when multiple IPv6 subnets on the same network
    was added to a dvr router, the internal snat ports were not
    appended with the IPv6 prefix properly.

    An error log message was thrown for the SNAT port not
    matching the given internal port for the IPv6 address.

    This patch will address this issue when IPv6 subnets are
    added or removed from the dvr router that are on the
    same network.
