BDB meta version log check bug

[gengjun-git]

https://github.com/apache/incubator-doris/blob/master/fe/fe-core/src/main/java/org/apache/doris/persist/EditLog.java#L515
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 LOG.error("meta data version is out of date, image: {}.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);
 }
