[LU-15597] add an LDLM flag to mark lock is saved to avoid extra commit

Wed, 2 Aug 2023 10:23:03 +0000

On DNE system a write lock held by a transaction will be saved after transaction stop, and once it receives REP-ACK, this lock will be downgraded, however in this period, if a conflicting write lock is enqueued, it should trigger a commit, but if we know this lock is not saved, a "sync" flag can be set to avoid commit, and the commit will be triggered in saving time.
