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>

+ Enable support for the Qualcomm Technologies HIDMA Management.
+ Each DMA device requires one management interface driver
+ for basic initialization before QCOM_HIDMA channel driver can
+ start managing the channels. In a virtualized environment,
+ the guest OS would run QCOM_HIDMA channel driver and the
+ host would run the QCOM_HIDMA_MGMT management driver.

+ The HIDMA controller supports optimized buffer copies
+ (user to kernel, kernel to kernel, etc.). It only supports
+ memcpy interface. The core is not intended for general
+ purpose slave DMA.
