[L3][IPv6][DVR] missing address scope mark for IPv6 traffic

[LIU Yulong]

There is a address sope mark iptables rule missing for IPv6 traffic of DVR router in compute node.
It should be part of the bug #1774463 , but IMO, we can fix it seperately [2].

    Any IPv6 traffic wants to go in/out directly on the DVR compute node
    will be dropped by the mis-configured scope mark iptables rule. This
