3.2.62-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Andrey Utkin <redacted>

[ Upstream commit 36beddc272c111689f3042bf3d10a64d8a805f93 ]

Setting just skb->sk without taking its reference and setting a
destructor is invalid. However, in the places where this was done, skb
is used in a way not requiring skb->sk setting. So dropping the setting
of skb->sk.
Thanks to Eric Dumazet [off-list ref] for correct solution.
