workqueue: Remove HK_TYPE_WQ from affecting wq_unbound_cpumask
For historical reason, wq_unbound_cpumask is initially set as
intersection of HK_TYPE_DOMAIN, HK_TYPE_WQ and workqueue.unbound_cpus
boot command line option.
At run time, users can update the unbound cpumask via the
/sys/devices/virtual/workqueue/cpumask sysfs file. Creation
and modification of cpuset isolated partitions will also update
wq_unbound_cpumask based on the latest HK_TYPE_DOMAIN cpumask.
The HK_TYPE_WQ cpumask is out of the picture with these runtime updates.
Complete the transition by taking HK_TYPE_WQ out from the workqueue code
and make it depends on HK_TYPE_DOMAIN only from the housekeeping side.
The final goal is to eliminate HK_TYPE_WQ as a housekeeping cpumask type.
