perf: Clarify perf_cpu_context::active_pmu usage by renaming it to ::unique_pmu
commit 3f1f33206c16c7b3839d71372bc2ac3f305aa802 upstream. Stephane thought the perf_cpu_context::active_pmu name confusing and suggested using 'unique_pmu' instead. This pointer is a pointer to a 'random' pmu sharing the cpuctx instance, therefore limiting a for_each_pmu loop to those where cpuctx->unique_pmu matches the pmu we get a loop over unique cpuctx instances.
