[SPARK-19751][SQL] Throw an exception if bean class has one's own class in
fields
## What changes were proposed in this pull request?
The current master throws `StackOverflowError` in
`createDataFrame`/`createDataset` if bean has one's own class in fields;
```
public class SelfClassInFieldBean implements Serializable {
private SelfClassInFieldBean child;
...
}
```
This pr added code to throw `UnsupportedOperationException` in that case as
soon as possible.
## How was this patch tested?
Added tests in `JavaDataFrameSuite` and `JavaDatasetSuite`.
