    Fix lost connection when create security group log

    Packet sent to table 91 are considered accepted by the egress pipeline
    and NORMAL action is used by default in this table. However, if we
    create a security group logging resource, then ovs flows log will be
    added into this table with higher priority. Therefore packet matches
    with ovs flows log will be sent to CONTROLLER and never forward.
    So this patch append action=NORMAL into ovs flows log to forward
    the packet and send it to CONTROLLER for logging.
