oprofile: warn on freeing event buffer too early
A race shouldn't happen since all workqueues or handlers are canceled or flushed before the event buffer is freed. A warning is triggered now if the buffer is freed too early. Also, this patch adds some comments about event buffer protection, reworks some code and adds code to clear buffer_pos during alloc and free of the event buffer.
