rcupreempt: fix hibernate/resume in presence of PREEMPT_RCU and hotplug
This fixes a oops encountered when doing hibernate/resume in presence of
PREEMPT_RCU.
The problem was that the code failed to disable preemption when
accessing a per-CPU variable. This is OK when called from code that
already has preemption disabled, but such is not the case from the
suspend/resume code path.
