ceph: save mon config even if failed to remove dead mon

During mon failover if the mon fails to be removed, the new mon
config was not being saved. The mon removal anyway is not retried
if it fails, so it should make a best effort to remove all the
resources related to the mon, and then always update the mon
config after the failover.
