DHT/Rebalance : Hard link Migration Failure
Probelm : __is_file_migratable used to return ENOTSUP for all the cases. Hence, it will add to the failure count. And the remove-brick status will show failure for all the files. Solution : Added 'ret = -2' to gf_defrag_handle_hardlink to be deemed as success. Otherwise dht_migrate_file will try to migrate each of the hard link, which not intended.
