Andrey Vagin f465fb249f net/unix: fix logic about sk_peek_offset 
commit e9193d60d3 upstream.

Now send with MSG_PEEK can return data from multiple SKBs.

Unfortunately we take into account the peek offset for each skb,
that is wrong. We need to apply the peek offset only once.

In addition, the peek offset should be used only if MSG_PEEK is set.
