rcu: Move rcu_is_nocb_cpu() from rcupdate.h to rcu.h
The rcu_is_nocb_cpu() function is used only internally to RCU. This commit therefore moves its declaration from include/linux/rcupdate.h to kernel/rcu/rcu.h. Reported-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
