I have abandoned https://review.openstack.org/86620 (first one above) in favor of https://review.openstack.org/86638 (second one above). The latter uses native cinder API calls for attachment and detachment of volumes and seems to work even on my local devstack, so I think that it is the way to fix this bug.
