ACPI DSMs can have an 'extended' status which can be non-zero to convey additional information about the command. In the xlat_status routine, where we translate the command statuses, we were returning an error for a non-zero extended status, even if the primary status indicated success. Return from each command's 'case' once we have verified both its status and extend status are good.
