rcu: Select IRQ_WORK from TREE_PREEMPT_RCU
TREE_RCU and TREE_PREEMPT_RCU both cause kernel/rcutree.c to be built,
but only TREE_RCU selects IRQ_WORK, which can result in an undefined
reference to irq_work_queue for some (random) configs:
kernel/built-in.o In function `rcu_start_gp_advanced':
kernel/rcutree.c:1564: undefined reference to `irq_work_queue'
Select IRQ_WORK from TREE_PREEMPT_RCU too to fix this.
