V4L/DVB (9499): cx88-mpeg: final fix for analogue only compilation + de-alloc fix

Browse Source 
Final fix for when analogue only is selected
for compilation (ie, !CX88_DVB)

This tidies up previous fix and adds missing
de-alloc memory leak on fault (eg, if fe1 fails to alloc
where fe0 was allocated).
