1533331 - Fix evergreen.protect_reserved_rows_from_delete() trigger function
The fix for bug
1513554 included creating a general trigger function to prevent
the deletion of reserved table rows with an ID lower than a specified threshold.
Testing for that seemed to pass muster, but using the function in practice revealed
a failure to delete deletable rows either.
This adds an explicit RETURN to the function, which fixes the issue.
