mimic: mds: fix corner case of replaying open sessions #28579
Marking a session dirty may flush all existing dirty sessions. MDS calls Server::finish_force_open_sessions() for log event that opens multiple sessions. The function marks sessions dirty one by one. So sessions opened by a log event may get flushed partially. When replaying a log event that opens multiple sessions, mds need to check if some of these sessions have already been flushed.
