netfilter: ipset: do not call ipset_nest_end after nla_nest_cancel
[ Upstream commit 708abf74dd87f8640871b814faa195fb5970b0e3 ]
In the error handling block, nla_nest_cancel(skb, atd) is called to
cancel the nest operation. But then, ipset_nest_end(skb, atd) is
unexpected called to end the nest operation. This patch calls the
ipset_nest_end only on the branch that nla_nest_cancel is not called.
