rcu-tasks: Mark RCU Tasks accesses to current->rcu_tasks_idle_cpu

The task_struct structure's ->rcu_tasks_idle_cpu can be concurrently
read and written from the RCU Tasks grace-period kthread and from the
CPU on which the task_struct structure's task is running.  This commit
therefore marks the accesses appropriately.
