89a8b69e9b avcodec/h264_cavlc: Check mb_skip_run 
Fixes: 10300/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_H264_fuzzer-6292205497483264

07e46226ae avcodec/h264_cavlc: Set valid qscale value in ff_h264_decode_mb_cavlc() 
When ff_h264_decode_mb_cavlc() failed due to wrong sl->qscale values,
e.g. dquant out of range, set the qscale to be a valid value before
returning -1 and exiting the function. The qscale value can be used
later e.g. in loop filter.

BUG=806122
