cluster/dht: A hard link is lost during rebalance + lookup

Problem:  A hard link is lost during rebalance + lookup.Rebalance skip files
          if file has hardlink.In dht_migrate_file __is_file_migratable ()
          function checks if a file has hardlink, if yes file is not migrated
          but if link is created after call this function then link will lost.

Solution: Call __check_file_has_hardlink to check hardlink existence after (S+T) bits
          in migration process ,if file has hardlink then skip the file for
          migrate rebalance process.
