[cinder] cinder-tempest-plugin-lvm-lio-barbican failures

The backup tests in the cinder-tempest-plugin-lvm-lio-barbican job have been failing for the past 24 hours or so. Luigi has a patch up that we think will fix this: https://review.opendev.org/c/openstack/cinder-tempest-plugin/+/777685 Until that merges, there's no point in rechecking cinder-tempest-plugin-lvm-lio-barbican failures. cheers, brian
