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.

+	  This loads the BL32 image for OP-TEE as firmware when the driver is
+	  probed. This returns -EPROBE_DEFER until the firmware is loadable from
+	  the filesystem which is determined by checking the system_state until
+	  it is in SYSTEM_RUNNING. This also requires enabling the corresponding
+	  option in Trusted Firmware for Arm. The documentation there explains
+	  the security threat associated with enabling this as well as
+	  mitigations at the firmware and platform level.
