[SPARK-11051][Core] Do not allow local checkpointing after the RDD is
materialized and checkpointed
JIRA: https://issues.apache.org/jira/browse/SPARK-11051
When a `RDD` is materialized and checkpointed, its partitions and
dependencies are cleared. If we allow local checkpointing on it and assign
`LocalRDDCheckpointData` to its `checkpointData`. Next time when the RDD is
materialized again, the error will be thrown.
