[PATCH] powerpc/pseries/cpuhp: fix non-NUMA build

[Nathan Lynch]

With CONFIG_NUMA unset, direct references to node_to_cpumask_map don't
work:

   arch/powerpc/platforms/pseries/hotplug-cpu.c: In function 'pseries_cpu_hotplug_init':
>> arch/powerpc/platforms/pseries/hotplug-cpu.c:1022:8: error: 'node_to_cpumask_map' undeclared (first use in this
>> function)
    1022 |        node_to_cpumask_map[node]);
	 |        ^~~~~~~~~~~~~~~~~~~

Use cpumask_of_node() here instead.
