ACPICA: Dispatcher: Fix order issue of method termination
The last step of the method termination should be the end of the method serialization. Otherwise, the steps happening after it will face the race issues that cannot be protected by the method serialization mechanism. This patch fixes this issue by moving the per-method-object deletion code prior than the end of the method serialization. Otherwise, the possible race issues may result in AE_ALREADY_EXISTS error in a parallel environment.
