[libvirt] [PATCH 3/5] Check against python None type when filling in auth parameters

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

When deciding whether to provide an auth function callback
in openAuth(), credcb was checked against NULL, when it
really needs to be checked against Py_None
