[SPARK-21269][Core][WIP] Fix FetchFailedException when enable 
maxReqSizeShuffleToMem and KryoSerializer

## What changes were proposed in this pull request?

 Spark **cluster** can reproduce, **local** can't:

1. Start a spark context with `spark.reducer.maxReqSizeShuffleToMem=1K` and 
`spark.serializer=org.apache.spark.serializer.KryoSerializer`:
```
$ spark-shell --conf spark.reducer.maxReqSizeShuffleToMem=1K --conf 
spark.serializer=org.apache.spark.serializer.KryoSerializer
```

2.  A shuffle:
```
scala> sc.parallelize(0 until 300, 10).repartition(2001).count()
```

The error messages:

```
org.apache.spark.shuffle.MetadataFetchFailedException: Missing an output 
location for shuffle 0
