This reworks current implementation of MSG_PEEK logic: 1) Replaces 'skb_queue_walk_safe()' with 'skb_queue_walk()'. There is no need in the first one, as there are no removes of skb in loop. 2) Removes nested while loop - MSG_PEEK logic could be implemented without it: just iterate over skbs without removing it and copy data from each until destination buffer is not full.
