[SPARK-17999][KAFKA][SQL] Add getPreferredLocations for KafkaSourceRDD
## What changes were proposed in this pull request?
The newly implemented Structured Streaming `KafkaSource` did calculate the preferred locations for each topic partition, but didn't offer this information through RDD's `getPreferredLocations` method. So here propose to add this method in `KafkaSourceRDD`.
## How was this patch tested?
Manual verification.
