Fixes: out of array access
Fixes: 21469/clusterfuzz-testcase-minimized-ffmpeg_AV_CODEC_ID_G2M_fuzzer-5199357982015488

73374013ff avcodec/cbs_h2645: Treat slices without data as invalid 
Slices that end after their header (meaning slices after the header
without any data before the rbsp_stop_one_bit or possibly without any
rbsp_stop_one_bit at all) are invalid and are now dropped. This ensures
that one doesn't run into two asserts in cbs_h2645_write_slice_data().

makes the code to remove them when decomposing slices dead code.
