Description

Remove duplicate logSync() and log message in FSN#enterSafemode()

FSN#enterSafemode(..)

      // Before Editlog is in OpenForWrite mode, editLogStream will be null. So,
      // logSyncAll call can be called only when Edlitlog is in OpenForWrite mode
      if (isEditlogOpenForWrite) {
        getEditLog().logSyncAll();
      }
      setManualAndResourceLowSafeMode(!resourcesLow, resourcesLow);
      NameNode.stateChangeLog.info("STATE* Safe mode is ON.\n" +
          getSafeModeTip());
      if (isEditlogOpenForWrite) {
        getEditLog().logSyncAll();
      }
      NameNode.stateChangeLog.info("STATE* Safe mode is ON" + getSafeModeTip());
