Move event resets from SignalCommandList to ComputeCommandList

Moves the call to event reset for the WaitEvent and AllResetEvent
to the ComputeCommandList.

This fixes a potential race condition where, if the SignalCommandList
executes before the ComputeCommandList, the WaitEvent could be reset
before the ComputeCommandList can wait on it and, consequently,
create a deadlock.
