OpenStackServer controller: minor log message fix

Fixes this bad error message format:

I0317 13:20:19.512088       1 openstackserver_controller.go:109] "OpenStackServer %s/%s linked to a Cluster that is paused. Won't reconcile" controllerGroup="infrastructure.cluster.x-k8s.io" controllerKind="OpenStackServer" OpenStackServer="sylva-system/management-cluster-cp-f7843e31d7-rbv5c" namespace="sylva-system" name="management-cluster-cp-f7843e31d7-rbv5c" reconcileID="a0e2f500-ae75-47af-bc3b-85bb9ae4b59b" sylva-system="management-cluster-cp-f7843e31d7-rbv5c"

We in fact don't need the "%s/%s" and also the additional paramters
aren't needed because the logger is derived from "scope" and already
logging the server name and namespace.
