The acpi_node_get_property_reference() doesn't return ACPI error codes,
it just returns regular negative kernel error codes. This patch doesn't
affect run time, it's just a clean up.

If "ret" is a Linux error code, should we print its value when reporting
the error so we know why the failure occurred, and propagate the error
code?

We can't propagate the error code because we might have failed because
acpi_node_get_property_reference() succeeded but it's not a device node.
