libperf cpumap: Take into advantage it is sorted to optimize perf_cpu_map__max()
From commit 7074674e7338863e ("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.
