Logging stack upgrade playbook fails

Issue

• Logging stack upgrade playbook is failing at TASK [openshift_logging_elasticsearch : set_fact]
• The task fails with the following fatal error message:

TASK [openshift_logging_elasticsearch : set_fact] ********************************************************************
fatal: [node.example.com]: FAILED! => {"msg": "The conditional check 'openshift_logging_elasticsearch_deployment_name == \"\"' failed. The error was: error while evaluating conditional (openshift_logging_elasticsearch_deployment_name == \"\"): 'None' has no attribute 'name'\n\nThe error appears to be in '/usr/share/ansible/openshift-ansible/roles/openshift_logging_elasticsearch/tasks/main.yaml': line 470, column 3, but may\nbe elsewhere in the file depending
on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- set_fact:\n  ^ here\n"}
********************************************************************

• There seems to be an issue in either roles/openshift_logging_elasticsearch/tasks/main.yaml': line 470, or roles/openshift_logging/tasks/install_logging.yaml: line 90.
