Alexander Shishkin af5bb4ed12 perf/ring_buffer: Document AUX API usage 
In order to ensure safe AUX buffer management, we rely on the assumption
that pmu::stop() stops its ongoing AUX transaction and not just the hw.

This patch documents this requirement for the perf_aux_output_{begin,end}()
APIs.
