    [OvS] Handle re_added multi ports

    Multiple ports are located in ports_re_added. Assume we have port_one
    and port_two. It will loop through the ports. Port_one is iterated
    first, events ['re_added'] is assigned port_one, events ['removed']
    is assigned port_two. In the second loop, events ['re_added'] is set
    to port_two instead of adding port_two to list. So after the loop,
    only port_two is left in events ['re_added'].
