[SRU X][PATCH 1/6] netfilter: xt_connlimit: don't store address in the conn nodes

From: Florian Westphal <fw at strlen.de>

BugLink: https://bugs.launchpad.net/bugs/1811094

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.
