  For now async vhost data path only supports split ring structure. In
order to make async vhost compatible with virtio 1.1 spec this patch
set cleans async split ring codes and enables packed ring in async
vhost data path. Batch datapath is also enabled in async vhost
packed ring.

v5:
 * clean some codes for packed ring datapath
 * fix an index error in shadow_ring_store()
v4:
  * change the patch structure
  * clean code for async split ring
  * reuse some code from split ring
  * change the error handler for DMA-copy packet
  * add check for malloc
  * remove useless code
  * add doc update
v3:
  * fix error handler for DMA-copy packet
v2:
  * fix wrong buffer index in rte_vhost_poll_enqueue_completed()
  * add async_buffers_packed memory free in vhost_free_async_mem()
