Subject: [PATCH] cpuset: fix compile warning when CONFIG_SMP=n

Reported by Fengguang's kbuild test robot:

kernel/cpuset.c:787: warning: 'generate_sched_domains' defined but not used

Introduced by commit e0e80a02e5701c8790bd348ab59edb154fbda60b
("cpuset: use rebuild_sched_domains() in cpuset_hotplug_workfn()),
which removed generate_sched_domains() from cpuset_hotplug_workfn().
