ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at gmail.com> | Wed Mar 24 01:14:24 2021 +0100| [63fcf3da018fd4c884d0780b90141ed22ed86016] | committer: Andreas Rheinhardt

avformat/utils: Remove redundant check

This check is outdated because the caller doesn't need to check that
the multiplication overflows when using av_realloc_array() (the code
in question used av_realloc() before that); furthermore, the check
is also a remnant of the time in which our allocation functions
didn't use size_t parameters.
