init,cpuset: fix initialize order
Impact: cpuset_wq should be initialized after init_workqueues()
When I read /debugfs/tracing/trace_stat/workqueues,
I got this:
# CPU INSERTED EXECUTED NAME
# | | | |
0 0 0 cpuset
0 285 285 events/0
0 2 2 work_on_cpu/0
0 1115 1115 khelper

1 0 0 ata/1

I found "cpuset" is at the earliest.
I found a create_singlethread_workqueue() is earlier than
init_workqueues():
kernel_init()
->cpuset_init_smp()
->create_singlethread_workqueue()
->do_basic_setup()
->init_workqueues()
I think it's better that create_singlethread_workqueue() is called
after workqueue subsystem has been initialized.
