What happened

使用milvus作为向量库，新建知识图谱或者向量类型的知识库时，上传第一个文件后，进行文件同步时报错DataNotMatchException: (code=1, message=The data doesn't match with schema fields, expect 4 list, got 20)；
目前测试的情况是只有第一个文件的第一次同步会报错。

What you expected to happen

只有新建的知识库在上传第一个文件进行同步时才会提示以上错误，初步定位到文件milvus_store的init_schema_and_load方法中，成员变量self.fields的字段长度应该是4，但是以上报错是因为它的长度变为20，其实是4个字段重复出现了5次，导致总共是20次，看起来像是线程不安全导致的问题

How to reproduce

1.构建一个知识图谱/向量类型的知识库；
2.上传一个文件；
3.选择上传的文件，点击"同步"
