[libvirt] PATCH: Fix fetch of NUMA info when building Xen capabilities

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

Currently if you use libvirt CVS HEAD on Xen >= 3.2 hypervisor it will fail
to open a connection. This is because I mistakenly removed the passing of
the virConnectPtr object when querying NUMA capabilities from XenD. This
patch fixes that regression
