ACPI: property: Release subnode properties with data nodes

struct acpi_device_properties describes one source of properties present
on either struct acpi_device or struct acpi_data_node. When properties are
parsed, both are populated but when released, only those properties that
are associated with the device node are freed.

Fix this by also releasing memory of the data node properties.
