netfilter: ipt_CLUSTERIP: fix warning unused variable cn
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") Signed-off-by: Anders Roxell <anders.roxell@linaro.org> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
