    Avoid error when removing addresses from address set

    There are race conditions [1] that can trigger address removal from
    address set, current code will result in a python exception:

       ValueError: list.remove(x): x not in list.

    Even worse, if address set is left inconsistent with neutron DB
    because of [1], e.g. an IP assigned to a port in neutron but not yet
    reflected in OVN address set, then future updates of IPs to that
    port will always fail on OVN side due to the exception above.
