[PATCH 2/4] rtla: Count all processed events

[Tomas Glozar]

Add a field processed_events to struct trace_instance and increment it
in collect_registered_events, regardless of whether a handler is
registered for the event.

The purpose is to calculate the percentange of events that were missed
due to tracefs buffer overflow.
