Translate msi address if device is behind virtio-iommu.
This logic is similar to vSMMUv3/Intel iommu emulation.
This RFC patch does not handle the case where both vsmmuv3 and
virtio-iommu are available.

This patch allows virtio-iommu protection for PCI
device-passthrough.
MSI region is mapped by current version of virtio-iommu driver.
This MSI region mapping in not getting pushed on hw iommu
vfio_get_vaddr() allows only ram-region. This RFC patch needed
