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.

+	help
+	  The Extended Industry Standard Architecture (EISA) bus was
+	  developed as an open alternative to the IBM MicroChannel bus.
+
+	  The EISA bus provided some of the features of the IBM MicroChannel
+	  bus while maintaining backward compatibility with cards made for
+	  the older ISA bus.  The EISA bus saw limited use between 1988 and
+	  1995 when it was made obsolete by the PCI bus.
+
+	  Say Y here if you are building a kernel for an EISA-based machine.
+
+	  Otherwise, say N.
+
+config EISA_VLB_PRIMING

+	default n
+	help
+	  Activate this option if your system contains a Vesa Local
+	  Bus (VLB) card that identify itself as an EISA card (such as
+	  the Adaptec AHA-284x).
+
+	  When in doubt, say N.
+
+config EISA_PCI_EISA
+	bool "Generic PCI/EISA bridge"
+	depends on !PARISC && PCI && EISA
+	default y
+	help
+	  Activate this option if your system contains a PCI to EISA
+	  bridge. If your system have both PCI and EISA slots, you
+	  certainly need this option.
+
+	  When in doubt, say Y.

+config EISA_VIRTUAL_ROOT
+	bool "EISA virtual root device"
+	depends on EISA && X86
+	default y
+	help
+	  Activate this option if your system only have EISA bus
+	  (no PCI slots).
+
+	  When in doubt, say Y.
+
+config EISA_NAMES
+	bool "EISA device name database"
+	depends on EISA
+	default y
+	help
+	  By default, the kernel contains a database of all known EISA
+	  device names to make the information in sysfs comprehensible
+	  to the user. This database increases size of the kernel
+	  image by about 40KB, but it gets freed after the system
+	  boots up, so it doesn't take up kernel memory. Anyway, if
+	  you are building an installation floppy or kernel for an
+	  embedded system where kernel image size really matters, you
+	  can disable this feature and you'll get device ID instead of
+	  names.
+
+	  When in doubt, say Y.
