Milian Wolff b13b04d938 perf script: Initialize zstd_data 
Fixes segmentation fault when trying to interpret zstd-compressed data
with perf script:

```
  $ perf record -z ls
  ...
  [ perf record: Captured and wrote 0,010 MB perf.data, compressed (original 0,001 MB, ratio is 2,190) ]
  $ memcheck perf script
  ...
