net/af_xdp: use single producer/consumer ring

Browse Source 
The ring is used only by af_xdp PMD itself, so no need to support
multi-producer and multi-consumer mode. This patch changes the ring
to single-producer and single-consumer mode, which could yield better
performance for addr enqueue and dequeue.
