Some netfilter compile errors when CONFIG_IPV6=m

[Cong Wang <amwang@redhat.com>]

Hi, all

I got the following compile errors when I compile IPv6 as a module and
most of the rest are built into core kernel. David Miller insists we
should fix this kind of error and not by adding Kconfig tricks.

net/built-in.o: In function `nf_tproxy_get_sock_v6':
/home/wangcong/linux/include/net/netfilter/nf_tproxy_core.h:177:
undefined reference to `udp6_lib_lookup'
/home/wangcong/linux/include/net/netfilter/nf_tproxy_core.h:177:

net/built-in.o: In function `tproxy_tg_init':

net/built-in.o: In function `socket_mt_init':
/home/wangcong/linux/net/netfilter/xt_socket.c:366: undefined reference
to `nf_defrag_ipv6_enable'
