iommu: Do not return error code for APIs with size_t return type Currently, iommu_unmap, iommu_unmap_fast and iommu_map_sg return size_t. However, some of the return values are error codes (< 0), which can be misinterpreted as large size. Therefore, returning size 0 instead to signify failure to map/unmap.
