Drop a table during log scanner scan records should fail the scanner

### Search before asking

- [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar.

### Motivation

1: start log scanner to scan a table
2: drop table
3: the scanner won't fail and log warning forever:
```
Received unknown table or bucket error in fetch for bucket TableBucket{tableId=29, bucket=0}
```

Actually I expect the log scanner can fail if found the table not exists any more.
