      Description

      This is a follow-up work for HDFS-13768. Mainly two places needed to update:

      • Add null check for add-replica pool to avoid lock acquiring
      • In ReplicaMap#addAndGet, it would be better to use FoldedTreeSet#addOrReplace instead of FoldedTreeSet#add for adding replica info. This is for the logic consistentency with add operation
