[41/50] : Fix IPV6 DAD handling

[Greg KH]

From: Denis V. Lunev <den@xxxxxxxxxx>

commit 9e3be4b34364a670bd6e57d2e8c3caabdd8d89f8 in mainline

addrconf_dad_failure calls addrconf_dad_stop which takes referenced address
and drops the count. So, in6_ifa_put perrformed at out: is extra. This
results in message: "Freeing alive inet6 address" and not released dst entries.
