ACPI: properties: Consistently return -ENOENT if there are no more references
commit babc92da5928f81af951663fc436997352e02d3a upstream. __acpi_node_get_property_reference() is documented to return -ENOENT if the caller requests a property reference at an index that does not exist, not -EINVAL which it actually does. Fix this by returning -ENOENT consistenly, independently of whether the property value is a plain reference or a package.
