This series fixes two issues with the perf_hwbreak test:
- Test fails on systems with large number of cpus due to hitting the 
  resource limit for maximum number of open file descriptors.
- Test fails on systems running with lower SMT levels since it assumes 
  all cpus are online.

Fix those issues. The first patch is a small cleanup to aid subsequent 
fixes.

  selftests/powerpc: Move perror closer to its use
  selftests/powerpc: Bump up rlimit for perf-hwbreak test
  selftests/powerpc: Account for offline cpus in perf-hwbreak test
