This patch implements asynchronous dequeue data path for split ring.
A new asynchronous dequeue function is introduced. With this function,
the application can try to receive packets from the guest with offloading
copies to the DMA engine, thus saving precious CPU cycles.
note: PATCH 2/4 depends on vhost patch from Jiayu Hu
