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.

+==============================
+The Linux Kernel documentation
+==============================
+
+This is the top level of the kernel's documentation tree.  Kernel
+documentation, like the kernel itself, is very much a work in progress;
+that is especially true as we work to integrate our many scattered
+documents into a coherent whole.  Please note that improvements to the
+documentation are welcome; join the linux-doc list at vger.kernel.org if
+you want to help out.
+
+Working with the development community
+======================================
+
+The essential guides for interacting with the kernel's development
+community and getting your work upstream.

+User-oriented documentation
+===========================
+
+The following manuals are written for *users* of the kernel — those who are
+trying to get it to work optimally on a given system and application
+developers seeking information on the kernel's user-space APIs.

+
+See also: the `Linux man pages <https://www.kernel.org/doc/man-pages/>`_,
+which are kept separately from the kernel's own documentation.

+
+Other documentation
+===================
+
+There are several unsorted documents that don't seem to fit on other parts
+of the documentation body, or may require some adjustments and/or conversion
+to reStructuredText format, or are simply too old.
