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>

+ Turns on optimized library functions (memcpy and memmove).
+ They are optimized by using word alignment. This will work
+ fine if both source and destination are aligned on the same
+ boundary. However, if they are aligned on different boundaries
+ shifts will be necessary. This might result in bad performance
