This change avoids accessing the segment map of the previous frame if segmentation is not enabled for the current frame. The caller of decode_mb_mode() only calls ff_thread_await_progress() on the reference segmentation index array if segmentation is enabled, so Chromium's TSAN will report a race when accessing this data while segmentation is not enabled.
