This check is still needed because some CSI plugins need to use secrets stored in SnapshotClass to delete the snapshot.

Then deletion will fail with some error msg in that case? I am ok to add it back. When I checked pv controller, I don't think they check storage class before deleting PV.

if err == nil {
ctrl.deleteSnapshot(newSnapshot)
}
ctrl.deleteSnapshot(snapshot)
return false
}
