netfilter: ipt_CLUSTERIP: fix warning unused variable cn
commit 206b8cc514d7ff2b79dd2d5ad939adc7c493f07a upstream.
When CONFIG_PROC_FS isn't set the variable cn isn't used.
net/ipv4/netfilter/ipt_CLUSTERIP.c: In function ‘clusterip_net_exit’:
net/ipv4/netfilter/ipt_CLUSTERIP.c:849:24: warning: unused variable ‘cn’ [-Wunused-variable]
struct clusterip_net *cn = clusterip_pernet(net);
^~
Rework so the variable 'cn' is declared inside "#ifdef CONFIG_PROC_FS".
Fixes: b12f7bad5ad3 ("netfilter: ipt_CLUSTERIP: remove wrong WARN_ON_ONCE in netns exit routine")
