avformat/avisynth: fix fallbacks for four frameprops

Browse Source 
If _FieldBased, _Matrix, _ColorRange, or _ChromaLocation haven't
been set, that absence would be interpreted as 0, leading to those
being set to case 0 instead of default. There is no case 0 for
_Primaries and _Transfer, so those were correctly falling back
to the default case.
