smp_call_function_any(): pass the node value to cpumask_of_node()
The change in acpi_cpufreq to use smp_call_function_any causes a warning
when it is called since the function erroneously passes the cpu id to
cpumask_of_node rather than the node that the cpu is on. Fix this.
cpumask_of_node(3): node > nr_node_ids(1)
