perf header: Sanity check HEADER_MEM_TOPOLOGY
Add validation to process_mem_topology() to harden against malformed
perf.data files:
- Upper bound check on nr_nodes (reuses MAX_NUMA_NODES, 4096)
- Minimum section size check before allocating
This is particularly important here since nr is u64, making unbounded
values especially dangerous.
