tracing fixes for 6.1:

Browse source

- Fix osnoise duration type to 64bit not 32bit.
 
 - Have histogram triggers be able to handle an unexpected NULL pointer
   for the record event, that can happen when the histogram first starts up.
 
 - Clear out ring buffers when dynamic events are removed, as the type
   that is saved in the ring buffer is used to read the event, and a
   stale type that is reused by another event could cause use after free
   issues.
 
 - Trivial comment fix.
 
 - Fix memory leak in user_event_create().
