Similar to commit 70f06c115b ("sched: act_ct: switch to per-action
label counting"), we should also switch to per-action label counting
in openvswitch conntrack, as Florian suggested.
The difference is that nf_connlabels_get() is called unconditionally
when creating an ct action in ovs_ct_copy_action(). As with these
flows:
table=0,ip,actions=ct(commit,table=1)
table=1,ip,actions=ct(commit,exec(set_field:0xac->ct_label),table=2)
it needs to make sure the label ext is created in the 1st flow before
the ct is committed in ovs_ct_commit(). Otherwise, the warning in
nf_ct_ext_add() when creating the label ext in the 2nd flow will
be triggered:
WARN_ON(nf_ct_is_confirmed(ct));
