The guest should run after resetting 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 resetting the guest,

This patch enables preservation of cpu runstate during save/load vm.
So when a vm is restored from snapshot, the cpu runstate is restored,
too.
See following example:
