Wei Wang e5645f51ba ipv6: release rt6->rt6i_idev properly during ifdown ... When a dst is created by addrconf_dst_alloc() for a host route or an anycast route, dst->dev points to loopback dev while rt6->rt6i_idev points to a real device. When the real device goes down, the current cleanup code only checks for dst->dev and assumes rt6->rt6i_idev->dev is the same. This causes the refcount leak on the real device in the above situation. This patch makes sure to always release the refcount taken on rt6->rt6i_idev during dst_dev_put().
