Patch fixing the issue

I've been testing some LOAS streams on Danish DVBT live tv.

On reading LOAS config, flag v=1 and vA=1 combination can sometimes occur,
leading to warning "Spec says "TBD"...".
Returning TRUE on this case while parameters 'sample_rate' and 'channels' are
pointing to uninitialized values can end on setting random values as rate and
channels on src caps.

I've added a simple patch initializing the concerned variables to fix this. I
think it's more secure to also return FALSE in this use case.
