rcu-tasks: Remove grace-period fast-path rcu-tasks helper
Now that the grace-period fast path can only happen during the pre-scheduler portion of early boot, this fast path can no longer block run-time RCU Tasks and RCU Tasks Trace grace periods. This commit therefore removes the conditional cond_resched_tasks_rcu_qs() invocation. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
