Description

~~LU-11125~~ indicates that there might be contention during recovery process on OFD, when objects are being re-created by resends and orphans are being destroyed at the same time by MDT. Both use os_create_lock mutex but it seems that is not necessary and each process can use own lock. Only the ostid_id should be changed under the same lock.
