This patchset introduces an unsafe API to get the number of inflight
packets in DMA engine. It should be only used within the vhost ops
which already holds the lock. Like vring state changes or device is
destroyed. Compared with rte_vhost_async_get_inflight(), this is a
lock free version.

RFC v1->v1:
* refine the doc and commit log

  vhost: add unsafe API to check inflight packets
  examples/vhost: use API to check inflight packets
