#7822: x264 possible encoding error with png source since N-93471-gf8fa8bbf22

Summary of the bug:
Last working build:
ffmpeg-20190325-6e42021-win64-static.zip
Up to now everything from ffmpeg-20190328-f8fa8bb-win64-static.zip and
later produces those errors.
Mplayer Home Cinema shows the error. ffdshow shows the error as well.
avidemux (latest build) does not show the decoding error, I can stream-
copy, but the resulting video still shows that error.
Tested with Ryzen 7 2700X on Windows 10 x64 1809 (latest updates) and on
i7-4960X on Server 2019 with latest updates: Same result although quite
different hardware.
Other CPU load does not matter, I/O load does not matter as well.
Reproduce:
Get test input data from from: http://www.joumxyzptlk.de/tmp/ffmpeg
/testdata-4k.7z
For comparison: Correct result with
ffmpeg-20190325-6e42021-win64-static.zip
