[PATCH] parted master return None when names are not supporeted

[Joel Granados Moreno <jgranado redhat com>]

Hello list

I just wanted to share an idea about how we should handle disks in
pyparted that do not support name.  I have not even tried to compile,
its just to show an example on how it might be done.

Regards.
