Fix possible access to undefined variable
g_glusterfs_hosts is verified to be defined in the beginning of the playbook. g_glusterfs_registry_hosts is only defined when playbooks/byo/openshift-cluster/cluster_hosts.yml is loaded, which seems to not always be the case. Instead of trying to find all entrypoints where cluster_hosts should be loaded to defined the variable, simply use the `default()` filter to consider it empty when not defined.
