Controller asserted in preparation of a role event due to the previous (same or another) role event preparation being not complete. Mayfly callee was disabled in the previous event due to the preparation time being short and previous start running (higher natural priority) before all previous preparation mayfly completed. The previous start disabled mayfly to avoid Radio ISR latencies. The current role event that asserted, preempted the previous role (observer role with continuous scanning window) which runs until preemption to maximise the Radio h/w use (observer scanning until next interval). The previous preparation mayfly is still disabled when the current role preparation tries to use same mayfly instance which should be free for a new enqueue. This commit updates mayfly implementation so that mayfly callee is disabled only after all enqueued mayfly instances are run to completion.
