[SPARK-15791] Fix NPE in ScalarSubquery
## What changes were proposed in this pull request?
The fix is pretty simple, just don't make the executedPlan transient in
`ScalarSubquery` since it is referenced at execution time.
## How was this patch tested?
I verified the fix manually in non-local mode. It's not clear to me why the
problem did not manifest in local mode, any suggestions?
