Subject: avcodec/decode: clean-up if get_hw_frames_parameters fails
https://trac.ffmpeg.org/ticket/11013
https://code.videolan.org/videolan/vlc/-/issues/28811
Fixes the following assert:
[00007f1df83d17e0] vaapi generic error: avcodec_get_hw_frames_parameters failed: -22
Assertion p_dst->hwaccel_threadsafe || (!dst->hwaccel && !dst->internal->hwaccel_priv_data) failed at libavcodec/pthread_frame.c:349
Reproduced from VLC with VAAPI, when fallbacking from hw to sw.
