ffmpeg | branch: release/5.1 | Christopher Degawa <ccom at randomderp.com> | Sun Nov 20 13:07:36 2022 -0600| [8fe2fec45321d1b82f98f9725ad9118cefcfa58d] | committer: Timo Rothenpieler

avcodec/libsvtav1: only set max_buf_sz if both bitrate and rc_buf_sz is set

maximum_buffer_size_ms should only be set if both are specified or if
the user sets it through -svtav1-params buf-sz=val
