rcu-tasks: Untrack blocked RCU Tasks Trace at reader end

This commit causes rcu_read_unlock_trace() to check for the current
task being on a per-CPU list within the rcu_tasks_percpu structure,
and removes it from that list if so.  This has the effect of curtailing
tracking of a task that blocked within an RCU Tasks Trace read-side
critical section once it exits that critical section.
