xen: swiotlb: return error code from xen_swiotlb_map_sg()
The .map_sg() op now expects an error code instead of zero on failure.
xen_swiotlb_map_sg() may only fail if xen_swiotlb_map_page() fails, but
xen_swiotlb_map_page() only supports returning errors as
DMA_MAPPING_ERROR. So coalesce all errors into EIO per the documentation
for dma_map_sgtable().
