The guest should run after reseting it, but it does not run if its
old state is RUN_STATE_INTERNAL_ERROR or RUN_STATE_PAUSED.

We don't set runstate to RUN_STATE_PAUSED when reseting the guest,
so the runstate will be changed from RUN_STATE_INTERNAL_ERROR or
RUN_STATE_PAUSED to RUN_STATE_RUNNING(not RUN_STATE_PAUSED).
