netdev: netdev_priv() can now be sane again.
The private area of a netdev is now at a fixed offset once more. Unfortunately, some assumptions that netdev_priv() == netdev->priv crept back into the tree. In particular this happened in the loopback driver. Make it use netdev->ml_priv. Signed-off-by: David S. Miller <davem@davemloft.net>
