ACPICA: Fix namespace race condition

Browse source

Fixes a race condition between method execution and namespace
walks that can possibly fault. Problem was apparently introduced
in version 20100528 as a result of a performance optimization
that reduces the number of namespace walks upon method exit
by using the delete_namespace_subtree function instead of the
delete_namespace_by_owner function used previously. Bug is in
the delete_namespace_subtree function.
