V4L/DVB (11079): au0828: fix panic on disconnect if analog initialization failed
If the analog initialization failed to create the video device, we never actually add the entry to the au0828_devlist. Therefore a panic occurs when unregistering the analog subsystem. Make it so we only remove the entry from the list if we added it to the list in the first place.
