### Description of PR
Fix for [HDFS-17870](https://issues.apache.org/jira/browse/HDFS-17870)
MiniDFSCluster.restartDataNode() throws ArrayIndexOutOfBoundsException when
attempting to restart a DataNode that was added to the cluster without
specifying storage capacities.
This bug is because MiniDFSCluster.setDataNodeStorageCapacities() did not
validate that the DataNode index is within the bounds of the storageCapacities
array before accessing it.
### How was this patch tested?
In
hadoop-hdfs-project/hadoop-hdfs/src/test/java/org/apache/hadoop/hdfs/TestMiniDFSCluster.java
add a new test method testRestartDataNodeWithoutStorageCapacities().
This test method will throw ArrayIndexOutOfBoundsException without the fix
and pass with the fix.
