      Description

      ReplicaInfo#unlinkBlock() is effectively disabled by the following code, because isUnlinked() always returns true.

      if (isUnlinked()) {
        return false;
      }
      

      Several test cases, e.g., TestFileAppend#testCopyOnWrite and TestDatanodeRestart#testRecoverReplicas are testing against the unlink
      Lets remove the relevant code to eliminate the confusions.

          I had a discussion with Colin P. McCabe offline and learned that ReplicaInfo#unlinkBlock was designed to append workload before HDFS-1700. It was not designed to remove the hardlinks created by DN upgrade.

          Since the code of creating hardlinks when appending a file is gone, the patch is still valid to remove dead code.
