GFS2: let spectator mount do read only recovery
Previously, a spectator mount would not even attempt to do journal recovery for a failed node. This meant that if all mounted nodes were spectators, everyone would be stuck after a node failed, all waiting for recovery to be performed. This is unnecessary since the failed node had a clean journal. Instead, allow a spectator mount to do a partial "read only" recovery, which means it will check if the failed journal is clean, and if so, report a successful recovery. If the failed journal is not clean, it reports that journal recovery failed. This makes it work the same as a read only mount on a read only block device.
