In https://github.com/ceph/ceph/pull/23958 an OSD will ping monitor
periodically now if it is stuck at __wait_for_healthy__. But in the
above case OSDs are still considering themselves as __active__ and
hence should miss that fixer.
Since these OSDs might be still able to contact with monitors (
otherwise there is no way for them to be marked up again) and send
beacons contiguously, we can simply get them out of the trap by
sharing some new maps with them.
