tracing: Call traceoff trigger after event is recorded
Call traceoff trigger after the event is recorded. Since current traceoff trigger is called before recording the event, we can not know what event stopped tracing. Typical usecase of traceoff/traceon trigger is tracing function calls and trace events between a pair of events. For example, trace function calls between syscall entry/exit. In that case, it is useful if we can see the return code of the target syscall.
