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.
