rcu/nocb: Initialize nocb kthreads only for boot CPU prior SMP initialization
The rcu_spawn_gp_kthread() function is called as an early initcall, which
means that SMP initialization hasn't happened yet and only the boot CPU is
online. Therefore, create only the NOCB kthreads related to the boot CPU.
