workqueue: require CPU hotplug read exclusion for apply_workqueue_attrs
Change the calling convention for apply_workqueue_attrs to require CPU
hotplug read exclusion.
Avoids lockdep complaints about nested calls to get_online_cpus in a
future patch where padata calls apply_workqueue_attrs when changing
other CPU-hotplug-sensitive data structures with the CPU read lock
already held.
