[fix](restore) avoid NPE for restore job (#36395)
## Proposed changes
Issue Number: close #36440
The indexes of OlapTable may not be assigned in method `readFields`:
```
@Override
public void readFields(DataInput in) throws IOException {
...
// read indexes
if (in.readBoolean()) {
this.indexes = TableIndexes.read(in);
}
...
}
```
So indexes may be null.
