powerpc: fix HOTPLUG error in rcutorture

I think we should avoid torture offline the cpu who do tick timer
when nohz full is running.

Tested on PPC VM of Open Source Lab of Oregon State University.
The test results show that after the fix, the success rate of
rcutorture is improved.
After:
Successes: 40 Failures: 9
Before:
Successes: 38 Failures: 11

I examined the console.log and Make.out files one by one, no new
compile error or test error is introduced by above fix.
