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.

v6:
* Fixed an issue of infinite loop.

v5:
* Rebased to the lastest branch.

v4:
* Added use case for API in vhost example.

v3:
* Fixed one typo.
* Revised the doc to be more accuracy.

v2:
* Fixed some format issues.
