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. Signed-off-by: Breno Leitao <leitao@debian.org> Signed-off-by: Tejun Heo <tj@kernel.org>

+ help
+ Enable reference count tracking for DPLL devices and pins.
+ This helps debugging reference leaks and use-after-free bugs
+ by recording stack traces for each get/put operation.
+
+ The tracking information is exposed via debugfs at:
+ /sys/kernel/debug/ref_tracker/dpll_device_*
+ /sys/kernel/debug/ref_tracker/dpll_pin_*
+
+ If unsure, say N.
