Do not wait for timer in ExDeleteTimer when closing VM.

Note: the timer should be cancelled already before reaching here.
Putting TRUE is just for feeling safe, as wait=TRUE should only
take effect when the timer is active. However, one of my AMD
PC would hang while all the other testing PCs are fine.
wait=FALSE can avoid the weird issue on that AMD PC.
