This patchset introduces a new API rte_vhost_async_dma_unconfigure()
to help user to manually free the DMA vchannel finished to use.

Note: this API should be called after async channel unregister.

v3:
* Rebase to latest DPDK.
* Refine some descriptions in the doc.
* Fix one bug in the vhost example.

v2:
* Add spinlock protection.
* Fix a memory leak issue.
* Refine the doc.
