Subject: [PATCH v6 net-next 1/3] net/sched: fix miss init the mru in qdisc_skb_cb

From: wenxu <wenxu@...oud.cn>

The mru in the qdisc_skb_cb should be init as 0. Only defrag packets in the
act_ct will set the value.

Fixes: 038ebb1a713d ("net/sched: act_ct: fix miss set mru for ovs after defrag in act_ct")
