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.

+Configuring Git
+===============
+
+This chapter describes maintainer level git configuration.
+
+Tagged branches used in pull requests (see
+Documentation/maintainer/pull-requests.rst) should be signed with the
+developers public GPG key. Signed tags can be created by passing
+``-u <key-id>`` to ``git tag``. However, since you would *usually* use the same
+key for the project, you can set it in the configuration and use the ``-s``
+flag. To set the default ``key-id`` use::
+
+	git config user.signingkey "keyname"
+
+Alternatively, edit your ``.git/config`` or ``~/.gitconfig`` file by hand::
+
+	[user]
+		name = Jane Developer
+		email = jd@domain.org
+		signingkey = jd@domain.org
+
+You may need to tell ``git`` to use ``gpg2``::
+
+	[gpg]
+		program = /path/to/gpg2
+
+You may also like to tell ``gpg`` which ``tty`` to use (add to your shell
+rc file)::
+
+	export GPG_TTY=$(tty)
