au0828: fix panic on disconnect if analog initialization failed
From: Devin Heitmueller <dheitmueller@linuxtv.org>
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.
Priority: normal
