[HAL]
We cannot make any assumptions about the latency whith which the timer interrupt fires after a rollover, since VBox (other VMs probably as well) doesn't always meet this. Add another check to KeQueryPerformanceCounter that gracefully handles missing interrupts. Also raise to DISPATCH_LEVEL, since the function is not reentrant.
