在启动FastDHT后又重启FastDFS的storage服务时报`dht_client/fdht_func.c, line: 361, invalid group count: 0 <= 0`错误

• 错误信息:

more /home/fdfs/storage/logs/storaged.log
[2021-11-02 21:17:23] ERROR - file: fdht_client/fdht_func.c, line: 361, invalid group count: 0 <= 0!
[2021-11-02 21:17:23] CRIT - exit abnormally!

• 错误原因: 通常两个原因，FastDHT 未配置成功（需要进一步验证是否正常运行），到成功运行工作时，验证storage接入FastDHT的参数是否有误。
