Return an empty stats if the container is restarting

Browse source 
In case, a container is restarting indefinitely running
"docker stats --no-stream <restarting_container>" is suspended.

To fix this, the daemon makes sure the container is either not
running or restarting if `--no-stream` is set to true and if so
returns an empty stats.

Should fix #27772.
