x86, UV: Fix smp_processor_id() use in a preemptable region
Fix a call by tunables_write() to smp_processor_id() within a
preemptable region.
Call get_cpu()/put_cpu() around the region where the returned
cpu number is actually used, which makes it non-preemptable.
A DEBUG_PREEMPT warning is prevented.
UV does not support cpu hotplug yet, but this is a step toward
that ability as well.
