workqueue: skip the node_nr_active update for non-unbound workqueuesgrafted

apply_wqattrs_commit() updates node_nr_active->max unconditionally.
wq->node_nr_active[] is only allocated for unbound workqueues, so guard
the call before per-cpu workqueues start using this path.

No functional change: only unbound workqueues reach apply_wqattrs_*()
today.

+
+Speakup is a kernel based screen review package for the linux operating
+system.  It allows blind users to interact with applications on the
+linux console by means of synthetic speech.
+
+Currently, speakup has one issue we know of.
+
+It seems to only happen on SMP systems. It seems that text in the output buffer
+gets garbled because a lock is not set. This bug happens regularly, but no one
+has been able to find a situation which produces it consistently.
+
+Patches, suggestions, corrections, etc, are definitely welcome.
+
+We prefer that you contact us on the mailing list; however, if you do
+not want to subscribe to a mailing list, send your email to all of the
