iommu: Propagate return value in ->attach_dev callback functions
The mtk_iommu and virtio drivers have places in the ->attach_dev callback functions that return hardcode errnos instead of the returned values, but callers of these ->attach_dv callback functions may care. Propagate them directly without the extra conversions.
