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".
