Please do not ignore Stephen Hemminger's feedback.

We already have enough odd SKB queue implementations, we
do not need yet another one in a core location.  This makes
it harder and harder to eventually convert sk_buff to use
"struct list_head".

Instead, use "struct sk_buff_head" and the lockless accessors
(__skb_insert, etc.) and initializer (__skb_queue_head_init).
