From: "Paul E. McKenney" <paul...@linux.vnet.ibm.com>
Tasks are no longer migrated to the root rcu_node, so there is no
longer any need for a boost kthread for the root rcu_node, and there no
longer is such a kthread. This commit therefore fixes the comment in
rcu_boost_kthread()'s header to reflect this new reality.
