Geo: don't create state records when not on Geo

https://gitlab.com/gitlab-org/gitlab/-/blob/11b69b846c28b4cc6c2a83c24188378c76e05cfe/ee/app/models/concerns/geo/verifiable_model.rb#L16 creates a state record for every replicated SSF datatype even when not on Geo - we want to introduce a guard clause to avoid that.
