Markus Mäkelä 3509aa144c Fix disable_master_role_setting in galeramon
The functionality to disable setting of master and slave status values to
Galera nodes was broken by the change to the monitoring algorithm.

The disable_master_role_setting option removed the master node which would
trigger the clearing of the replication status values from the node. A
more direct, and arguably better, way is to check that this option is
disabled before processing the status values for the nodes.
