Riccardo Mancini 6e93bc534f libperf cpumap: Take into advantage it is sorted to optimize perf_cpu_map__max()
From commit 7074674e73 ("perf cpumap: Maintain cpumaps ordered and
without dups"), perf_cpu_map elements are sorted in ascending order.

This patch improves the perf_cpu_map__max function by returning the last
element.

Committer notes:

Do it as a ternary to keep it in just one return line, add a comment
explaining it is sorted and what functions does it.
