net: add prefetch() in skb_defer_free_flush()
skb_defer_free_flush() is becoming more important these days.
Add a prefetch operation to reduce latency a bit on some
platforms like AMD EPYC 7B12.
On more recent cpus, a stall happens when reading skb_shinfo().
Avoiding it will require a more elaborate strategy.
