[xuan.ding at intel.com]

From: Xuan Ding <xuan.ding at intel.com>

This patchset introduces an unsafe API to get the number of inflight
packets in DMA engine in some situations. Like vring state changes or
device is destroyed. Compared with rte_vhost_async_get_inflight(),
this is a lock free version.
