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.

+	tristate "Industrial I/O support"
+	help
+	  The industrial I/O subsystem provides a unified framework for
+	  drivers for many different types of embedded sensors using a
+	  number of different physical interfaces (i2c, spi, etc).

+	  acquisition methods.

+config IIO_CONFIGFS
+	tristate "Enable IIO configuration via configfs"
+	select CONFIGFS_FS
+	help
+	  This allows configuring various IIO bits through configfs
+	  (e.g. software triggers). For more info see
+	  Documentation/iio/iio_configfs.rst.
+
+config IIO_GTS_HELPER
+	tristate
+
+config IIO_TRIGGER
+	bool "Enable triggered sampling support"
+	help
+	  Provides IIO core support for triggers.  Currently these
+	  are used to initialize capture of samples to push into
+	  buffers.  The triggers are effectively a 'capture
+	  data now' interrupt.
+
+config IIO_CONSUMERS_PER_TRIGGER
+	int "Maximum number of consumers per trigger"
+	depends on IIO_TRIGGER
+	default "2"
+	help
+	  This value controls the maximum number of consumers that a
+	  given trigger may handle. Default is 2.

+config IIO_SW_DEVICE
+	tristate "Enable software IIO device support"

+	help
+	  Provides IIO core support for software devices. A software

+	  using the API provided.

+	select IIO_TRIGGER
+	help
+	  Provides helper functions for setting up triggered events.
+
+config IIO_BACKEND
+	tristate
+	help
+	  Framework to handle complex IIO aggregate devices. The typical
+	  architecture that can make use of this framework is to have one
+	  device as the frontend device which can be "linked" against one or
+	  multiple backend devices. The framework then makes it easy to get
+	  and control such backend devices.
