[libvirt] [PATCH 1/5] remote: Fix incorrect use of private data field

[Jiri Denemark]

From: Daniel Berrange <berrange at redhat.com>

NodeDeviceCreateXML and NodeDeviceDestroy methods added for NPIV were
using the wrong privateData field for the remote driver. This doesn't
impact KVM, since the remote driver handles everything, thus
privateData == devMonPrivateData. It does impact Xen though, because
the remote driver only handles a subset of methods and thus
privateData != devMonPrivateData.
