ACPICA: Namespace: Change namespace override to avoid node deletion
ACPICA commit c0ce529e1fbb8ec47d2522a3aa10f3ab77e16e41
There is no reference counting implemented for struct acpi_namespace_node, so it
is currently not removable during runtime.
This patch changes the namespace override code to keep the old
struct acpi_namespace_node undeleted so that the override mechanism can happen
during runtime. Bob Moore.
