net: prefech skb->priority in __dev_xmit_skb()
Most qdiscs need to read skb->priority at enqueue time().
In commit 100dfa74cad9 ("net: dev_queue_xmit() llist adoption")
I added a prefetch(next), lets add another one for the second
half of skb.
Note that skb->priority and skb->hash share a common cache line,
so this patch helps qdiscs needing both fields.
