Register sysfs for workqueue iscsi_destroy, so that users can set cpu affinity
through "cpumask" for this workqueue to get better isolation in cloud
multi-tenant scenario.
This patch unfolded create_singlethread_workqueue(), added WQ_SYSFS and drop
__WQ_ORDERED_EXPLICIT since __WQ_ORDERED_EXPLICIT workqueue isn't allowed to
change "cpumask".
