Srikar Dronamraju caa8e29da5 powerpc/smp: Optimize start_secondary
In start_secondary, even if shared_cache was already set, system does a
redundant match for cpumask. This redundant check can be removed by
checking if shared_cache is already set.

While here, localize the sibling_mask variable to within the if
condition.
