avcodec/hevc_cabac: Check prefix so as to avoid invalid shifts in coeff_abs_level_remaining_decode() I suspect that this can be limited tighter, but i failed to find anything in the spec that would confirm that. Fixes: 4833/clusterfuzz-testcase-minimized-5302840101699584 Fixes: runtime error: left shift of 134217730 by 4 places cannot be represented in type 'int' Found-by: continuous fuzzing process https://github.com/google/oss-fuzz/tree/master/projects/ffmpegSigned-off-by:Michael Niedermayer <michael@niedermayer.cc>
