    [ovn] Specify port type if it's a router port when updating
    
    In order to avoid multiple LogicalSwitchPortUpdateUpEvent and
    LogicalSwitchPortUpdateDownEvent is mandatory to specify the
    router port type when udpating the port.
    
    If the port is not specified when updating the port, the
    transactions will trigger a modification on the ovnnb db
    that will set the port status to down[0]. Triggering an unnecessary
    DownEvent followed by another UpEvent. Those unnecessary event
    most likely will trigger a revision conflict.
