nvdec: implement flush/drain

In the first case (flush) you'd like to get all frames discarded ASAP, while in
the second all pending frames should go downstream.

Is this correctly handled, is it possible to do the flushing faster without
trying to push frames downstream first? Note also that pushing a frame
downstream with return FLUSHING, which might stop it from outputting (and thus
discarding) any further frames?
