Special Scenario 2: SVA Is Not Supported. All Devices Registered with the UACCE Do Not Support the IOMMU Scenario

In this scenario, the involved interfaces are described in Special Scenario 2: SVA Is Not Supported. All Devices Registered with the UACCE Do Not Support the IOMMU Scenario and no interface is added.

After the memory is reserved by using the memory reservation function interface, if the pointer needs to be transferred to the hardware, the user-mode address needs to be converted to the address visible to the hardware by using wd_blk_iova_map during the send process, and the hardware-visible address needs to be converted to the user-mode address by using wd_blk_iova_unmap during the recv process.

Note that the adaptation code may be removed.
