[SPARK-4433] fix a racing condition in zipWithIndex
Spark hangs with the following code:
~~~
sc.parallelize(1 to 10).zipWithIndex.repartition(10).count()
~~~
This is because ZippedWithIndexRDD triggers a job in getPartitions and it
causes a deadlock in DAGScheduler.getPreferredLocs (synced).
This should be applied to branch-1.0, branch-1.1, and branch-1.2.
