This bug was introduced with https://github.com/ansible-collections/openvswitch.openvswitch/pull/88 Because https://github.com/ansible-collections/openvswitch.openvswitch/blob/2.1.1/plugins/modules/openvswitch_db.py#L299 out will never be defined when running in check_mode (https://github.com/ansible-collections/openvswitch.openvswitch/blob/2.1.1/plugins/modules/openvswitch_db.py#L292-L294)
