[PATCH v2 5/8] perf cpumap: Clean up use of perf_cpu_map__has_any_cpu_or_is_empty

[Ian Rogers]

Most uses of what was perf_cpu_map__empty but is now
perf_cpu_map__has_any_cpu_or_is_empty want to do something with the
CPU map if it contains CPUs. Replace uses of
perf_cpu_map__has_any_cpu_or_is_empty with other helpers so that CPUs
within the map can be handled.
