[SPARK-16173] [SQL] Can't join describe() of DataFrame in Scala 2.10
## What changes were proposed in this pull request?
This PR fixes `DataFrame.describe()` by forcing materialization to make the `Seq` serializable. Currently, `describe()` of DataFrame throws `Task not serializable` Spark exceptions when joining in Scala 2.10.
## How was this patch tested?
Manual. (After building with Scala 2.10, test on `bin/spark-shell` and `bin/pyspark`.)
