To implement dGPU prime feature, virtgpu needs to import/export buffer
between virtio iGPU and passthrough dGPU. Before that, virtgpu should
check if P2P is possible or not. But calling function pci_p2pdma_distance
in guest VM will only get virtual p2pdma_distance instead of real physical
p2pdma_di
