[SPARK-11749][Streaming] Duplicate creating the RDD in file stream when
recovering from checkpoint data
Add a transient flag `DStream.restoredFromCheckpointData` to control the
restore processing in DStream to avoid duplicate works: check this flag first
in `DStream.restoreCheckpointData`, only when `false`, the restore process will
be executed.
