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.
Fixes: c343bc2ce2c6 ("ACPI: properties: Align return codes of __acpi_node_get_property_reference()")
