avcodec/osq: Fix signed integer overflow in update_stats()
Fixes: negation of -2147483648 cannot be represented in type 'int'; cast to an unsigned type to negate this value to itself
Fixes: 410109093/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_OSQ_fuzzer-6550900028276736
Note, none of the available osq files uses update_stats(), this change may fix or break
files using coding_mode == 2. The code prior looks wrong though
