recoverd: Improve error messages on recovery lock coherence fail
When the daemon is able to take the recovery lock during recovery we
might as well guess that the cluster filesystem has a lock coherence
problem and print a more useful message. This will be more helpful to
those trying out cluster filesystems that don't have lock coherence or
that are difficult to setup.
