[PATCH] netfilter: fix clusterip_net_exit build regression

From: Arnd Bergmann
Date: Thu Dec 07 2017 - 08:27:18 EST


The added check produces a build error when CONFIG_PROC_FS is
disabled:

net/ipv4/netfilter/ipt_CLUSTERIP.c: In function 'clusterip_net_exit':
net/ipv4/netfilter/ipt_CLUSTERIP.c:822:28: error: 'cn' undeclared (first use in this function)

This moves the variable declaration out of the #ifdef to make it
available to the WARN_ON_ONCE().

Fixes: 613d0776d3fe ("netfilter: exit_net cleanup check added")
