ACPICA: Namespace: Properly null terminate objects detached from a namespace node
commit e23d9b82 upstream. Fixes a bug exposed by an ACPICA unit test around the acpi_attach_data()/acpi_detach_data() APIs where the failure to null terminate a detached object led to the creation of a circular linked list (and infinite looping) when the object is reattached.
