rcutorture: Traverse possible cpu to set maxcpu in rcu_nocb_toggle()

Currently, the maxcpu is set by traversing online CPUs, however, if the
rcutorture.onoff_holdoff is set zero and onoff_interval is set non-zero,
and the some CPUs with larger cpuid has been offline before setting
maxcpu, for these CPUs, even if they are online again, also cannot
be offload or deoffload.  This can result in rcutorture attempting to
(de-)offload CPUs that have never been online, but the (de-)offload code
handles this.

This commit therefore use for_each_possible_cpu() instead of
for_each_online_cpu() in rcu_nocb_toggle().
