net/sched: act_api: fix miss set post_ct for ovs after do conntrack in act_ct
When openvswitch conntrack offload with act_ct action. The first rule do conntrack in the act_ct in tc subsystem. And miss the next rule in the tc and fallback to the ovs datapath but miss set post_ct flag which will lead the ct_state_key with -trk flag. Fixes: 7baf2429a1a9 ("net/sched: cls_flower add CT_FLAGS_INVALID flag support") Signed-off-by: wenxu <wenxu@ucloud.cn> Reviewed-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S.
