[BUG] 在使用了JSONWriter.Feature.WriteClassName后，FastJson2无法正确处理Map<String, Integer>

### 问题描述

我有一个类
```
public static class TestState {

Map currentTerm;

public TestState(Map currentTerm) {
this.currentTerm = currentTerm;
}
}
```
如果我在序列化时使用了`JSONWriter.Feature.WriteClassName`，那么在反序列化处理时，FastJson2在处理`currentTerm`时会报错`com.alibaba.fastjson2.JSONException: parseInt error, value : java.util.HashMap`

### 环境信息

- OS信息： Ubuntu 22.04.3 LTS
- JDK信息： Oracle JDK 1.8.0_421
- 版本信息：Fastjson2 2.0.53

### 重现步骤

可使用下列完整单元测试代码来复现该缺陷

```
import java.util.Map;

import org.junit.jupiter.api.Test;

import com.alibaba.fastjson2.JSON;
import com.alibaba.fastjson2.JSONObject;
import com.alibaba.fastjson2.JSONReader;
import com.alibaba.fastjson2.JSONWriter;
import com.alibaba.fastjson2.filter.Filter;

public class TestFastJSON {

public static class TestState {

Map currentTerm;

public TestState(Map currentTerm) {
this.currentTerm = currentTerm;
}
}

private static final Filter autoTypeFilter = JSONReader.autoTypeFilter(
"com.",
"org.",
"java.",
"edu.");

public JSONWriter.Feature[] features = new JSONWriter.Feature[] {
JSONWriter.Feature.WriteClassName,
JSONWriter.Feature.FieldBased,
};

public JSONReader.Feature[] readerFeatures = new JSONReader.Feature[] {
JSONReader.Feature.FieldBased,
};

@Test
void testFastJSON() {
Map currentTerm = new java.util.HashMap<>();
currentTerm.put("N1", 2);
currentTerm.put("N2", 2);
currentTerm.put("N3", 1);
TestState ts = new TestState(currentTerm);
String stateJSONStr = JSONObject.toJSONString(ts, features);
TestState deseriObj = JSON.parseObject(stateJSONStr, TestState.class,
autoTypeFilter,
readerFeatures);
}
}
```

将上述代码复制到任意支持Junit 5的测试框架中，运行`testFastJSON`单元测试，可观察到完整报错信息如下：

```

### 期待的正确结果

可以正确的将TestState反序列化

### 相关日志输出

如上

#### 附加信息

无

Start by running the complete JUnit 5 test in testFastJSON with Fastjson2 2.0.53 and inspect the stack path through JSONReader.java, JSONReaderUTF16.java, ObjectReaderImplInteger.java, ObjectReaderImplMapTyped.java, and ObjectReaderAdapter.java. Add regression coverage for the shown TestState and Map case; done means deserialization completes without the parseInt error.
