Subject: [PATCH net 1/7] netfilter: nfnetlink_queue: silence bogus compiler warning

From: Florian Westphal <fw@...len.de>

net/netfilter/nfnetlink_queue.c:601:36: warning: variable 'ctinfo' is
uninitialized when used here [-Wuninitialized]
   if (ct && nfnl_ct->build(skb, ct, ctinfo, NFQA_CT, NFQA_CT_INFO) < 0)

ctinfo is only uninitialized if ct == NULL.  Init it to 0 to silence this.
