appletalk: Fix socket referencing in skb
[ 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 <eric.dumazet@gmail.com> for correct solution.
