Subject: [PATCH v6 2/2] vhost: enable IOMMU for async vhost

The use of IOMMU has many advantages, such as isolation and address
translation. This patch extends the capbility of DMA engine to use IOMMU if
the DMA engine is bound to vfio.

When set memory table, the guest memory will be mapped into the default
container of DPDK.
