[SPARK-16432] Empty blocks fail to serialize due to assert in
ChunkedByteBuffer
## What changes were proposed in this pull request?
It's possible to also change the callers to not pass in empty chunks, but
it seems cleaner to just allow `ChunkedByteBuffer` to handle empty arrays. cc

## How was this patch tested?
Unit tests, also checked that the original reproduction case in
https://github.com/apache/spark/pull/11748#issuecomment-230760283 is resolved.
