The error comes from CreateSnapshot call validation, https://github.com/kubernetes/cloud-provider-openstack/blob/f1704c89ae2ca0da43969887f80d0913f2f738cd/pkg/csi/manila/util.go#L206
I.e. the volume snapshot class used by the test does not have `csi.storage.k8s.io/snapshotter-secret-name` and `csi.storage.k8s.io/snapshotter-secret-namespace` parameters.

I think there are two issues with it, both should be fixed in the operator (I don't have OCP cluster with Manila):
1. The operator must file the secrets in the default volume snapshot class. Right now, there are not such parameters: https://github.com/openshift/csi-driver-manila-operator/blob/master/assets/volumesnapshotclass.yaml
2. The CSI test manifests must declare that VolumeSnapshotClasses created in the tests should be copied from from the default one, i.e. use SnapshotClass.FromExistingClassName: <the default volume snapshot class>
