[Bug 111111] Corrupted output with vaapi 10 bit -> 8 bit transcoding on AMD RAVEN

Bug ID: 11
   Summary: Corrupted output with vaapi 10 bit -> 8 bit
transcoding on AMD RAVEN
   Product: Mesa
   Version: git
  Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
  Severity: normal
  Priority: medium
 Component: Drivers/Gallium/radeonsi
  Assignee: dri-devel@lists.freedesktop.org
  Reporter: gre...@outlook.com
QA Contact: dri-devel@lists.freedesktop.org

Initially, I've filled ffmpeg bug since vaapi transcoding 10 bit > 8 bit was
just failing, someone refereed to a "separated field of surfaces bug" which I
couldn't find and offered patch which fixed the initial issue here:
https://trac.ffmpeg.org/ticket/7764

After applying patch transcoding goes through with significant speed increase
[from 2x to 7x] but the resulting output has flashing green overlay/glitch in
upper half of the video. 

E.g from command"
ffmpeg -threads 4 \
-init_hw_device vaapi=amd:/dev/dri/renderD128 -hwaccel vaapi
-hwaccel_output_format vaapi -hwaccel_device amd -filter_hw_device amd \
-i trk.mkv \
-vf "scale_vaapi=format=nv12,hwupload" \
-c:v h264_vaapi  -profile:v 578 \   
-c:a copy -bf 0 -c:s copy \
-f mpegts -y plop.mkv

Input is any 10 bit hevc video.
