[SPARK-16582][SQL] Explicitly define isNull = false for non-nullable
expressions
## What changes were proposed in this pull request?
This patch is just a slightly safer way to fix the issue we encountered in
https://github.com/apache/spark/pull/14168 should this pattern re-occur at
other places in the code.
## How was this patch tested?
Existing tests. Also, I manually tested that it fixes the problem in
SPARK-16514 without having the proposed change in
https://github.com/apache/spark/pull/14168
