vaapidecode: always reset decoder on ::set_format().

Browse source 
Split GstVideoDecoder::set_format() handler to first update the sink
pad caps and reset the active VA decoder instance based on those, and
then update the src pad caps whenever possible, e.g. when the caps
specify a valid video resolution.
