Eric Vaughn a943188dab tracing/user_events: Optimize safe list traversals 
Several of the list traversals in the user_events facility use safe list
traversals where they could be using the unsafe versions instead.

Replace these safe traversals with their unsafe counterparts in the
interest of optimization.
