Subject: [PATCH 12/23] netfilter: xt_connlimit: don't store address in the conn nodes

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

Only stored, never read.  This is a leftover from commit 7d08487777c8
("netfilter: connlimit: use rbtree for per-host conntrack obj storage"),
which added the rbtree node struct that stores the address instead.
