Subject: [PATCH 04/13] Revert "netfilter: xt_connlimit: connlimit-above early loop termination"

From: Stefan Berger <stefanb@...ux.vnet.ibm.com>

This reverts commit 44bd4de9c2270b22c3c898310102bc6be9ed2978.

I have to revert the early loop termination in connlimit since it generates
problems when an iptables statement does not use -m state --state NEW before
the connlimit match extension.
