Encoding with h264_amf is corrupted when using d3d11va hwaccel and d3d11 as hardware output format

Description
http://samples.ffmpeg.org/benchmark/testsuite1/matrixbench_mpeg2.mpg
./ffmpeg -hwaccel d3d11va -hwaccel_output_format d3d11 -i matrixbench_mpeg2.mpg -an -c:v h264_amf out.mkv
The above produces a stream with tons of stutter, and a different result each time (varying checksum).
Using nv12 instead as output format fixes it.
I'm using an HD7950 on Windows 10 x64 (version 1709, Fall Creators build), driver version 17.12.1
I don't know if this also happens with other GPU vendors as i can't test, and of course software encoders will not accept d3d11 pixfmt as input.

h264_nvenc seems to work fine, so changing this into an AMF bug.
