[PATCH 02/25] perf tools: Use perf_cpu_map__nr instead of cpu_map__nr

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Jiri Olsa <jolsa@kernel.org>

Switch the rest of the perf code to use libperf's perf_cpu_map__nr(),
which is the same as current cpu_map__nr() and remove the cpu_map__nr()
function.
