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>

+How to compile perf for Android
+===============================
+
+There are two ways to build perf and run it on Android:
+
+- Method 1: Build perf with static linking. See Build.txt, section
+ "4) Cross compilation" for how to build a static perf binary.
+
+- Method 2: Download the Android NDK and use the bundled Clang to
+ build perf. See Build.txt, section "5) Build with clang" for details.
