s390/numa: let NODES_SHIFT depend on NEED_MULTIPLE_NODES
[ Upstream commit 64438e1bc0cdbe6d30bcdcb976f935eb3c297adc ]
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.
