I don't believe that it's currently safe to use get_css_set() on a zero-refcount css_set anyway - a css_set starts with refcount 1 and can be freed the moment that its refcount reaches 0. You can only use get_css_set() on a stable reference to an existing css_set, which by definition has a refcount of at least 1. Were you thinking of any particular existing uses?
