[SPARK-25368][SQL] Incorrect predicate pushdown returns wrong result
How to reproduce:
```scala
val df1 = spark.createDataFrame(Seq(
(1, 1)
)).toDF("a", "b").withColumn("c", lit(null).cast("int"))
val df2 = df1.union(df1).withColumn("d",
spark_partition_id).filter($"c".isNotNull)
df2.show
+---+---++---+
| a| b| c| d|
+---+---++---+
| 1| 1|null| 0|
| 1| 1|null| 1|
+---+---++---+
```
`filter($"c".isNotNull)` was transformed to `(null <=> c#10)` before
https://github.com/apache/spark/pull/19201, but it is transformed to `(c#10 =
null)` since https://github.com/apache/spark/pull/20155. This pr revert it to
`(null <=> c#10)` to fix this issue.
unit tests
Closes #22368 from wangyum/SPARK-25368.
