net: openvswitch: Fix matching zone id for invalid conns arriving from tc

BugLink: https://bugs.launchpad.net/bugs/1959376
[ Upstream commit 635d448a1cce4b4ebee52b351052c70434fa90ea ]

Zone id is not restored if we passed ct and ct rejected the connection,
as there is no ct info on the skb.

Save the zone from tc skb cb to tc skb extension and pass it on to
ovs, use that info to restore the zone id for invalid connections.

Fixes: d29334c15d33 ("net/sched: act_api: fix miss set post_ct for ovs after do conntrack in act_ct")
