esp6: Fix scatterlist initialization

When we use IPsec extended sequence numbers, we may overwrite the last scatterlist of the associated data by the scatterlist for the skb. This patch fixes this by placing the scatterlist for the skb right behind the last scatterlist of the associated data. esp4 does it already like that.
