[SPARK-11376] [SQL] Removes duplicated `mutableRow` field

This PR fixes a mistake in the code generated by `GenerateColumnAccessor`. 
Interestingly, although the code is illegal in Java (the class has two fields 
with the same name), Janino accepts it happily and accidentally works properly.

$ git pull https://github.com/liancheng/spark spark-11376.fix-generated-code

Experimented with the following snippet:

```scala
  ...
  evaluator.cook(
s"""private String a = null;
   |
   |private Integer a = null;
   |
   |@Override
   |public int add(int lhs, int rhs) {
   |  System.out.println(a);
   |  return lhs + rhs;
   |}
 """.stripMargin
  )
  ...
```

Janino doesn't complain as long as the duplicated fields are either both 
null or not referenced.
