Subject: [PATCH] net: sched: act_connmark: don't zap skb->nfct

This action is meant to be passive, i.e. we should not alter
skb->nfct: If nfct is present just leave it alone.

Compile tested only.

shouldn't matter much in practice since this would be used in the
ingress path where skb->nfct is NULL in non-lo case.
