    [OVS FW] Clean port rules if port not found in ovsdb
    
    During e.g. migration or shelve of VM it may happend that
    port update event will be send to the ovs agent and in the almost
    the same time, port will be removed from br-int.
    In such case during update_port_filter method openvswitch firewall
    driver will not find port in br-int, and it will do nothing with it.
    That will lead to leftover rules for this port in br-int.
    
    So this patch adds calling remove_port_filter() method if port was
    not found in br-int. Just to be sure that there is no any leftovers
    from the port in br-int anymore.
