BDB meta version log check bug

Version check using MetaContext seems meaningless. Code should be

         if (version > FeConstants.meta_version) {
                LOG.error("meta data version is out of date, image: {}. meta: {}."
                     + "please update FeConstants.meta_version and restart.",
                     MetaContext.get().getMetaVersion(), FeConstants.meta_version);
                System.exit(-1);
         }
