    Migrate device_owner for router's interface

    When migrating a HA router to legacy, the router's interface (whose
    device_owner is network:ha_router_replicated_interface) isn't changed
    to network:router_interface. This means that certain actions (such as
    trying to use 'neutron router-interface-delete' and migrating the router
    to DVR) won't work (since a router interface of the appropriate type
    can't be found and an SNAT port won't be created, respectively). This
    patch takes care of the needed migration.
