### Description of PR
In LineRecordReader, we may open a filestream:
```
fileIn = FutureIO.awaitFuture(builder.build());
```
However, we may be interrupted or otherwise throw an error before `in` is
initialized, for example here:
```
fileIn.seek(start);
```
If this happens, the caller has no way to close this file stream causing it
to leak.
### How was this patch tested?
Existing tests.
### For code changes:
- [x] Does the title or this PR starts with the corresponding JIRA issue id
(e.g. 'HADOOP-17799. Your PR title ...')?
- [ ] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies
licensed in a way that is compatible for inclusion under [ASF
2.0](http://www.apache.org/legal/resolved.html#category-a)?
- [ ] If applicable, have you updated the `LICENSE`, `LICENSE-binary`,
`NOTICE-binary` files?
