mds: handle cache rejoin corner case

A recovering MDS may receives strong cache rejoin from a survivor,
then the survivor restarts, the recovering MDS receives week cache
rejoin from the same MDS. Before processing the week cache rejoin,
we should scour replicas added by the obsoleted strong cache rejoin.
