[libvirt] PATCH: Fix python binding for listing storage pools/volumes
The python binding for the APIs to list storage pools and volumes has a hand written C layer, but an auto-generated python layer. The latter was auto-generating incorrectly, so this patch overrides its API contract making the generator work correctly. Dan.

Looks fine, so we added to the C module but didn't override in the XML, right ?

Yes, I missed it because the generator was quite happy generating code for them. I just didn't notice the code it was generating was broken !
