Title: [SPARK-2402] Update the initial position when reuse DiskBlockObjectWriter

Minor fix, `initialPosition` can not be updated after `close()` and re`open()`, which will lead to error when reusing this object. Details can be seen in [SPARK-2402](https://issues.apache.org/jira/browse/SPARK-2402).
