Since a788f227 "memory: Allow replay of IOMMU mapping notifications"
when new VFIO listener is added, all existing IOMMU mappings are replayed.
However there is a problem that the base address of an IOMMU memory region
(IOMMU MR) is ignored which is not a problem for the existing user (which is
pseries) with its default 32bit DMA window starting at 0 but it is if there is
another DMA window.
This adjusts the replaying address by mr->addr.
