ipv6: statically link register_inet6addr_notifier()
Tomas reported the following build error:
net/built-in.o: In function `ieee80211_unregister_hw':
(.text+0x10f0e1): undefined reference to `unregister_inet6addr_notifier'
net/built-in.o: In function `ieee80211_register_hw':
(.text+0x10f610): undefined reference to `register_inet6addr_notifier'
make: *** [vmlinux] Error 1
when built IPv6 as a module.
So we have to statically link these symbols.
