[SRU][F:linux-bluefield][PATCH 3/8] net/sched: fix miss init the mru in qdisc_skb_cb

[Bodong Wang]

From: wenxu <wenxu at ucloud.cn>

BugLink: https://bugs.launchpad.net/bugs/1940872

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")
