[FFmpeg-cvslog] avcodec/mpegvideo_enc: Remove always-false checks

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Wed Oct  4 21:57:53 2023 +0200| [5aaaa7dbee959947fbb4f8f58cfd2a388725c09e] | committer: Andreas Rheinhardt

avcodec/mpegvideo_enc: Remove always-false checks

In case "!direct" we are not reusing the input buffers
(due to e.g. insufficient alignment), but allocating
new ones. These of course do not alias with the ones
provided by the user, so these checks are always-false.
