When a Veritas Cluster Server agent reported a service group with only Frozen/TFrozen entries and no State entry (partial VCS output), the VCS Service Group check crashed with ValueError: 'summary' must be non-empty str or None.

Such service groups now no longer crash. As there is no state information for the group, the check simply reports no state result for it; any active freeze and the cluster name are still shown.
