avcodec/v4l2_context: don't reinit output queue on dynamic resolution change event
Reference: linux/Documentation/userspace-api/media/v4l/dev-decoder.rst "During the resolution change sequence, the OUTPUT queue must remain streaming. Calling VIDIOC_STREAMOFF() on the OUTPUT queue would abort the sequence and initiate a seek. In principle, the OUTPUT queue operates separately from the CAPTURE queue and this remains true for the duration of the entire resolution change sequence as well."
