At present, there are two situations which the rcu callback function
be exectued in the kthreads, one is if the use_softirq is set to zero,
the RCU_SOFTIRQ processing is carried out by the per-CPU rcuc kthreads,
for non-offload rdp, the rdp's rcu callback function be exectued in rcuc
kthreads. another one is if the rdp is set to offloaded, the rdp's rcu
callback function be exected in the rcuop kthreads.
