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.
