ACPI: properties: Consistently return -ENOENT if there are no more re…

…ferences

commit babc92d 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.
