Fixed galeramon not setting server status for downed servers

If galeramon isn't able to connect to a Galera node, the server state is left
unaltered. This will cause servers that lose connectivity to be in RUNNING|JOINED
state which causes them to be assigned with the SLAVE status. For servers that are
never accessible, the state will be RUNNING.
