[Devel] [PATCH] ve: fix container stopped state check

[Stanislav Kinsburskiy]

Checking for empty cgroup is not correct, because init process leaves cgroup
early in do_exit.
This leads to a situation, when container is treated as stopped but its
resources (VEIP for instance) are not yet released.
Which in turn leads to container restart failure due to non-releases VEIP
address.
