[Libvir] Ensure errors are reported against virConnect object

In xend_internal.c there are a large number of places where errors are being reported without supplying an associated virConnectPtr object. So for example when calling virDomainCreateLinux, some errors get associated with the connection object, while others get attached to the global error object. The attached patch fixes up all places in xend_internal.c which have an virConnectPtr object available to always pass this object into the the error reporting funcs.
