Arnaldo Carvalho de Melo 22a2e2b292 perf header: Sanity check HEADER_CPU_TOPOLOGY ...

Add validation to process_cpu_topology() to harden against malformed
perf.data files:

- Verify nr_cpus_avail was initialized (HEADER_NRCPUS processed first)
- Bounds check sibling counts (cores, threads, dies) against nr_cpus_avail
- Fix two bare 'return -1' that leaked env->cpu by using 'goto free_cpu'
