Pull probe fixes from Masami Hiramatsu:

 - tprobe-events: Fix to register tracepoint correctly

   tprobe-events missed to set tracepoint data structure before
   registering callback when enabling it. This sets it correctly.

 - tprobe-events: Fix to put tracepoint_user when disable the event

   tprobe-events missed to unregister tracepoint callback when the event
   is disabled. This ensures to unregister it.
