检查RDBMS配置项时，存在逻辑错误

module: plugin-rdbms-util
class: com.alibaba.datax.plugin.rdbms.reader.util.OriginalConfPretreatmentUtil
line 263 ~ 267
code:
```java
1. if (!ListUtil.checkIfValueSame(tableModeFlags)
2. || !ListUtil.checkIfValueSame(tableModeFlags)) {
3. throw DataXException.asDataXException(DBUtilErrorCode.TABLE_QUERYSQL_MIXED,
4. "您配置凌乱了. 不能同时既配置table又配置querySql. 请检查您的配置并作出修改.");
5. }
```
此处行2的检查应该是`querySqlModeFlags`，否则无法正确提示存在不同querySql的connection配置

Start in plugin-rdbms-util at com.alibaba.datax.plugin.rdbms.reader.util.OriginalConfPretreatmentUtil, around lines 263-267, and compare the two checks with the surrounding table and querySql configuration handling. Done means the validation checks the intended querySql flags and correctly detects inconsistent querySql connection configuration; run the relevant RDBMS reader tests if available.
