Hi.

With the latest Linux 4.2-rc1, I am hitting this build error with GCC
4.4.7 on CentOS 6.

  CC      net/netfilter/ipset/ip_set_hash_netnet.o
net/netfilter/ipset/ip_set_hash_netnet.c: In function
‘hash_netnet4_uadt’:

Previously fixed with commit 1a869205c75cb ("netfilter: ipset: The
unnamed union initialization may lead to compilation error"),
reintroduced with commit aff227581ed1a ("netfilter: ipset: Check CIDR
value only when attribute is given").

I wonder what can be done to get this issue fixed. This problem was seen
in 4.2-rc1 and now in 4.2-rc2 on RHEL-6.6.

Just revert the initializer piece.
