rcu: Use kthread_create_on_node()
Commit a26ac2455ffc (move TREE_RCU from softirq to kthread) added
per-CPU kthreads. However, kthread creation uses kthread_create(), which
can put the kthread's stack and task struct on the wrong NUMA node.
Therefore, use kthread_create_on_node() instead of kthread_create()
so that the stacks and task structs are placed on the correct NUMA node.
A similar change was carried out in commit 94dcf29a11b3 (kthread:
use kthread_create_on_node()).
Also change rcutorture's priority-boost-test kthread creation.
