When the legacy Xen driver probes with a NULL URI, and finds itself running on Xen, it will set conn->uri. A little bit later though it checks to see if libxl support exists, and if so declines the driver. This leaves the conn->uri set to 'xen:///', so if libxl also declines it, it prevents probing of the QEMU driver.
Once a driver has set the conn->uri, it must *never* decline an open request. So we must move the libxl check earlier
