From: Stanislaw Kardach <k...@semihalf.com>
For dev_ops not supported by the secondary process, either return -EPERM
or return without doing anything. In both cases log a warning.
It's still application's responsibility to avoid calls like that and
those changes are for debugging/informational purposes.
