ipa: raspberrypi: AWB: Ignore invalid statistics zones correctly

Browse source 
Regions of the image where the statistics are not trusted should not
be put in the zones_ list.

This also means that the AWB may fail to run initially, so
async_results_ needs to be initialised to some kind of default.

Finally, the RGB zone structures can be zero-initialised safely now,
the previous value of -1 would seem unusual.
