YNL currently reports None for empty dump:

 $ cli.py ...netdev.yaml --dump page-pool-get
 None

This doesn't matter for the CLI but when writing YNL based tests
having to deal with either list or None is annoying. Limit the
None conversion to non-dump ops:

 $ cli.py ...netdev.yaml --dump page-pool-get
 []
