[ Upstream commit 1b1f57cf9e4c8eb16c8f6b2ce12cc5dd3517fc61 ]
ASan reports several memory leak while running:
# perf test "82: Use vfs_getname probe to get syscall args filenames"
One of the leaks is caused by zstd data not being released on exit in
perf-script.
This patch adds the missing zstd_fini().
