rcu: Kconfig help needs to say that TREE_PREEMPT_RCU scales down

To quote Valdis:

    This leaves somebody who has a laptop wondering which
    choice is best for a system with only one or two cores that
    has CONFIG_PREEMPT defined. One choice says it scales down
    nicely, the other explicitly has a 'depends on PREEMPT'
    attached to it...

So add "scales down nicely" to TREE_PREEMPT_RCU to match that of
TREE_RCU.
