Javadoc

Check whether checksum needs to be verified. Skip verifying checksum iff this is not the last one in the pipeline and clientName is non-null. i.e. Checksum is verified on all the datanodes when the data is being written by a datanode rather than a client. Whe client is writing the data, protocol includes acks and only the last datanode needs to verify checksum.
