[FFmpeg-cvslog] avcodec/get_buffer: Don't get AVPixFmtDescriptor unnecessarily

[Andreas Rheinhardt]

ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Mon Aug 15 10:18:22 2022 +0200| [f76cef5c518a9874ec4e3b4b36c5b909c3452919] | committer: Andreas Rheinhardt

avcodec/get_buffer: Don't get AVPixFmtDescriptor unnecessarily

It is unused since 3575a495f6dcc395656343380e13c57d48b9f976
(and the error message is dangerous: av_get_pix_fmt_name(format)
returns NULL iff av_pix_fmt_desc_get(format) returns NULL
and using a NULL string for %s would be UB).
