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This check is outdated because the caller doesn't need to check that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.
