rcu/nocb: Move nocb field at the end of state struct

Browse source

nocb_is_setup is a rarely used field, mostly on boot and CPU hotplug.
It shouldn't occupy the middle of the rcu state hot fields cacheline.

Move it to the end and build it conditionally while at it. More cold
NOCB fields are to come.
