virtio-iommu: Rename reserved_regions into prop_resv_regions

Rename VirtIOIOMMU (nb_)reserved_regions fields with the "prop_" prefix
to highlight those fields are set through a property, at machine level.
They are IOMMU wide.

A subsequent patch will introduce per IOMMUDevice reserved regions
that will include both those IOMMU wide property reserved
regions plus, sometimes, host reserved regions, if the device is
backed by a host device protected by a physical IOMMU. Also change
nb_ prefix by nr_.
