2.2.9 btrfs: File loss on log replay after renaming a file and fsync

If a file is renamed and fsynced and a system crash or power outage occurs, when the log is replayed, the file is deleted because the last_unlink_trans value is not captured in the log of the inode leaving the log without enough information to later replay the rename operation. (Bug ID 23725060)
