When running "gst-gst-device-monitor-1.0 Video", device monitor probes device providers one by one and sends bus message to gst-device-monitor to print device information. There is one case that libcameraprovider and v4l2deviceprovider both exit, libcameraprovider fails to probe device while v4l2deviceprovider probes successfully. "gst-device-monitor Video" will show nothing as v4l2deviceprovider is hidden and the bus message it uses to convey device information is dropped. To fix this issue, not to hide v4l2deviceprovider when do gst_libcamera_provider_init().
