Review comment:
If this check is true means, the state is transitioned to shutdown, we call
stop() and terminate. So, datanode process is terminated.

> Recently we have seen an issue, in InitDatanodeState, there is error during
> create Path for volume. We set the state to shutdown and this has caused
> DatanodeStateMachine to stop, but datanode is still running. In this case we
> should stop Datanode, otherwise, user will know about this when running ozone
> commands or when user observed metrics like healthy nodes.
