Subject: ipv6: assign rt6_info to inet6_ifaddr in init_loopback
From: Gao feng <gaofeng@xxxxxxxxxxxxxx>
[ Upstream commit 534c877928a16ae5f9776436a497109639bf67dc ]
Commit 25fb6ca4ed9cad72f14f61629b68dc03c0d9713f
"net IPv6 : Fix broken IPv6 routing table after loopback down-up"
forgot to assign rt6_info to the inet6_ifaddr.
When disable the net device, the rt6_info which allocated
in init_loopback will not be destroied in __ipv6_ifa_notify.
This will trigger the waring message below
[23527.916091] unregister_netdevice: waiting for tap0 to become free. Usage count = 1
