ipv6: don't call addrconf_dst_alloc again when enable lo
[ Upstream commit a881ae1f625c599b460cc8f8a7fcb1c438f699ad ]
If we disable all of the net interfaces, and enable
un-lo interface before lo interface, we already allocated
the addrconf dst in ipv6_add_addr. So we shouldn't allocate
it again when we enable lo interface.
Otherwise the message below will be triggered.
unregister_netdevice: waiting for sit1 to become free. Usage count = 1
This problem is introduced by commit 25fb6ca4ed9cad72f14f61629b68dc03c0d9713f
