memory: Remove IOMMU MR iommu_set_iova_range API 

Since the host IOVA ranges are now passed through the
PCIIOMMUOps set_host_resv_regions and we have removed
the only implementation of iommu_set_iova_range() in
the virtio-iommu and the only call site in vfio/common,
let's retire the IOMMU MR API and its memory wrapper.
