workqueue: copy workqueue_attrs with all fields

commit 2865a8fb44cc32420407362cbda80c10fa09c6b2 upstream.

 $echo '0' > /sys/bus/workqueue/devices/xxx/numa
 $cat /sys/bus/workqueue/devices/xxx/numa

I got 1. It should be 0, the reason is copy_workqueue_attrs() called
in apply_workqueue_attrs() doesn't copy no_numa field.

Fix it by making copy_workqueue_attrs() copy ->no_numa too.  This
would also make get_unbound_pool() set a pool's ->no_numa attribute
according to the workqueue attributes used when the pool was created.
While harmelss, as ->no_numa isn't a pool attribute, this is a bit
confusing.  Clear it explicitly.

tj: Updated description and comments a bit.
