Liang-Chi Hsieh 5b8b324f33 [SPARK-6303][SQL] Remove unnecessary Average in GeneratedAggregate ... Because `Average` is a `PartialAggregate`, we never get a `Average` node when reaching `HashAggregation` to prepare `GeneratedAggregate`. That is why in SQLQuerySuite there is already a test for `avg` with codegen. And it works. But we can find a case in `GeneratedAggregate` to deal with `Average`. Based on the above, we actually never execute this case. So we can remove this case from `GeneratedAggregate`.
