alpha: return error code from alpha_pci_map_sg()
The .map_sg() op now expects an error code instead of zero on failure.
pci_map_single_1() can fail for different reasons, but since the only
supported type of error return is DMA_MAPPING_ERROR, we coalesce those
errors into EIO.
ENOMEM is returned when no page tables can be allocated.
