ACPI: device property: Fix node lookup in acpi_graph_get_child_prop_value()
acpi_graph_get_child_prop_value() is intended to find a child node with a
certain property value pair. The check
if (!fwnode_property_read_u32(fwnode, prop_name, &nr))
continue;
is faulty: fwnode_property_read_u32() returns zero on success, not on
failure, leading to comparing values only if the searched property was not
found.
Moreover, the check is made against the parent device node instead of
the child one as it should be.
