ACPICA: Namespace: Properly null terminate objects detached from a namespace node

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.

Reported in acpica bugzilla #1063
