[SPARK-18634][SQL][TRIVIAL] Touch-up Generate

## What changes were proposed in this pull request? I jumped the gun on merging apache#16120, and missed a tiny potential problem. This PR fixes that by changing a val into a def; this should prevent potential serialization/initialization weirdness from happening. ## How was this patch tested? Existing tests. Author: Herman van Hovell <[email protected]> Closes apache#16170 from hvanhovell/SPARK-18634.
