ipv6: fix missing in6_ifa_put in addrconf
Fix ref count bug introduced by
commit 2de795707294972f6c34bae9de713e502c431296
Author: Lorenzo Colitti <lorenzo@google.com>

ipv6: addrconf: don't remove address state on ifdown if the address
is being kept
Fix logic so that addrconf_ifdown() decrements the inet6_ifaddr
refcnt correctly with in6_ifa_put().
