Paul E. McKenney 33f137143e ftrace: Use asynchronous grace period for register_ftrace_direct() ...

When running heavy test workloads with KASAN enabled, RCU Tasks grace
periods can extend for many tens of seconds, significantly slowing
trace registration.  Therefore, make the registration-side RCU Tasks
grace period be asynchronous via call_rcu_tasks().
