s390/numa: let NODES_SHIFT depend on NEED_MULTIPLE_NODES
Qian Cai reported: """ When NUMA=n and nr_node_ids=2, in apply_wqattrs_prepare(), it has, for_each_node(node) { if (wq_calc_node_cpumask(... where it will trigger a booting warning, WARNING: workqueue cpumask: online intersect > possible intersect because it found 2 nodes and wq_numa_possible_cpumask[1] is an empty cpumask. """ Let NODES_SHIFT depend on NEED_MULTIPLE_NODES like it is done on other architectures in order to fix this.
