avcodec/wavpack: Fix overflow in p=31
Untested with "non fuzzed" samples as i have no such file
The reference 5.6.0 decoder appears to also have undefined behavior in the lossless codepath for this
Fixes: shift exponent 32 is too large for 32-bit type 'int'
Fixes: 50930/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_WAVPACK_fuzzer-6319201949712384
Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpeg
