drm/i915/pmu: replace cpumask_weight with cpumask_empty where appropriate
i915_pmu_cpu_online() calls cpumask_weight() to check if any bit of a
given cpumask is set. We can do it more efficiently with cpumask_empty()
because cpumask_empty() stops traversing the cpumask as soon as it finds
first set bit, while cpumask_weight() counts all bits unconditionally.
