[libvirt] [PATCH] udev: only report a warning if udev_enumerate_scan_devices fails

Even if an error is reported by `udev_enumerate_scan_devices`, e.g. because a driver of a device has an bug, we can still enumerate all other devices. Additionally the documentation of udev_enumerate_scan_devices says that on success an integer >= 0 is returned (see man udev_enumerate_scan_devices(3)).
