Accept sPAPR errno for DMA range overflow The DMA map limit test expects an overflowing IOVA range to fail with -EOVERFLOW. That matches the Type1 and iommufd paths.
On sPAPR TCE v2, the same invalid range is rejected as outside the active TCE window and currently returns -ENXIO. Treat that as the expected ppc result for this RFC while keeping the existing -EOVERFLOW expectation for other backends. This keeps the overflow test enabled for sPAPR TCE v2 instead of skipping it.
