avcodec/dovi_rpu: Use 64 bit in get_us/se_coeff()
Fixes: shift exponent 32 is too large for 32-bit type 'int'
Fixes: 63151/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_HEVC_fuzzer-5067531154751488
Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg
