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.

+ * struct madera_codec_pdata
+ *
+ * @max_channels_clocked: Maximum number of channels that I2S clocks will be
+ *			  generated for. Useful when clock master for systems
+ *			  where the I2S bus has multiple data lines.
+ * @dmic_ref:		  Indicates how the MICBIAS pins have been externally
+ *			  connected to DMICs on each input. A value of 0
+ *			  indicates MICVDD and is the default. Other values are:
+ *			  For CS47L35 one of the CS47L35_DMIC_REF_xxx values
+ *			  For all other codecs one of the MADERA_DMIC_REF_xxx
+ *			  Also see the datasheet for a description of the
+ *			  INn_DMIC_SUP field.
+ * @inmode:		  Mode for the ADC inputs. One of the MADERA_INMODE_xxx
+ *			  values. Two-dimensional array
+ *			  [input_number][channel number], with four slots per
+ *			  input in the order
+ *			  [n][0]=INnAL [n][1]=INnAR [n][2]=INnBL [n][3]=INnBR
+ * @out_mono:		  For each output set the value to TRUE to indicate that
+ *			  the output is mono. [0]=OUT1, [1]=OUT2, ...
+ * @pdm_fmt:		  PDM speaker data format. See the PDM_SPKn_FMT field in
+ *			  the datasheet for a description of this value.
+ * @pdm_mute:		  PDM mute format. See the PDM_SPKn_CTRL_1 register
+ *			  in the datasheet for a description of this value.
