From: Arnd Bergmann <a...@arndb.de>
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")
