Some of the per-CPU masks use cpu_cpu_mask as a filter to limit the search
for related CPUs. On a dlpar add of a CPU, update cpu_cpu_mask before
updating the per-CPU masks. This will ensure the cpu_cpu_mask is updated
correctly before its used in setting the masks. Setting the numa_node will
ensure that when cpu_cpu_mask() gets called, the correct node number is
used. This code movement helped fix the above call trace.
