workqueue: workqueue_cpu_callback() should be cpu_notifier instead of hotcpu_notifier
Commit 6ee0578b (workqueue: mark init_workqueues as early_initcall) made workqueue SMP initialization depend on workqueue_cpu_callback(), which however was registered as hotcpu_notifier() and didn't get called if CONFIG_HOTPLUG_CPU is not set. This made gcwqs on non-boot CPUs not create their initial workers leading to boot failures. Fix it by making it a cpu_notifier.
