rcu: Remove "select IRQ_WORK" from config TREE_RCU
The 48a7639ce80c ("rcu: Make callers awaken grace-period kthread") removed the irq_work_queue(), so the TREE_RCU doesn't need irq work any more. This commit therefore updates RCU's Kconfig and Signed-off-by: Lai Jiangshan <laijs@cn.fujitsu.com> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
