Revert "workqueue: Override implicit ordered attribute in workqueue_apply_unbound_cpumask()"
This reverts commit ca10d851b9ad0338c19e8e3089e24d565ebfffd7. The commit allowed workqueue_apply_unbound_cpumask() to clear __WQ_ORDERED on now removed implicitly ordered workqueues. This was incorrect in that system-wide config change shouldn't break ordering properties of all workqueues. The reason why apply_workqueue_attrs() path was allowed to do so was because it was targeting the specific workqueue - either the workqueue had WQ_SYSFS set or the workqueue user specifically tried to change max_active, both of which indicate that the workqueue doesn't need to be ordered. The implicitly ordered workqueue promotion was removed by the previous commit 3bc1e711c26b ("workqueue: Don't implicitly make UNBOUND workqueues w/ @max_active==1 ordered"). However, it didn't update this path and broke build. Let's revert the commit which was incorrect in the first place which also fixes build.
