avvidec: Report the latency once we're fully configured
Several decoders will only be able to report a real latency (has_b_frames)
once they're actually initialized (i.e. when they return their first frame).
Doing it earlier (in set_format) doesn't guarantee that the AVCodecContext
has_b_frames has been properly initialized.
