netfilter: ipt_CLUSTERIP: fix build error without procfs
We can't access c->pde if CONFIG_PROC_FS is disabled: net/ipv4/netfilter/ipt_CLUSTERIP.c: In function 'clusterip_config_find_get': net/ipv4/netfilter/ipt_CLUSTERIP.c:147:9: error: 'struct clusterip_config' has no member named 'pde' This moves the check inside of another #ifdef. Fixes: 6c5d5cfbe3c5 ("netfilter: ipt_CLUSTERIP: check duplicate config when initializing") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
