    [stable only] Do not fail on missing logical router ports

    set_gateway_mtu runs for all the gateway ports for a network
    and if one of the ports get's deleted in meanwhile
    whole transaction fails.

    To handle this we need to add if_exists=True to the transaction
    but for that it needs to be supported in ovsdbapp. It's fixed
    in ovsdbapp with [1] but would require to bump ovsdbapp
    minimal version in requirements.txt which we normally don't
    do for stable branches.

    So using "update_lrouter_port" instead as that have the
    required option available. Before [2] that was only used
    but during the switch if_exists part was missed.
