Grow: stop previous reshape process first
If array is stopped during reshape and assembled again straight away, reshape process in a background might still be running. systemd doesn't start a new service if one already exists. If there is a race, previous process might terminate and new one is not created. Reshape doesn't continue after assemble. Tell systemd to restart the service rather than just start it. It will assure previous service is stopped first. If it's not running, stopping has no effect and only new process is started.
