Note: this API should be called after async channel unregister. v5: * Use mutex instead of spinlock. * Improve code readability. v4: * Rebase to 22.11 rc1. * Fix the usage of 'dma_ref_count' to make sure the specified DMA device is not used by any vhost ports before unconfiguration. 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.
