[PATCH 12/20] netfilter: ipset: Use the stored first cidr value instead of '1'

[pablo@netfilter.org]

From: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu>

The stored cidr values are tried one after anoter. The boolean
condition evaluated to '1' instead of the first stored cidr or
the default host cidr.
