Arnd Bergmann 56ef587b77 stable-fixup: hotplug: fix unused function warning ...

[resolves a messed up backport, so no matching upstream commit]

The backport of upstream commit 777c6e0dae ("hotplug: Make
register and unregister notifier API symmetric") to linux-4.4.y
introduced a harmless warning in 'allnoconfig' builds as spotted by
kernelci.org:

kernel/cpu.c:226:13: warning: 'cpu_notify_nofail' defined but not used [-Wunused-function]

So far, this is the only stable tree that is affected, as linux-4.6 and
higher contain commit 984581728e ("cpu/hotplug: Split out cpu down functions")
that makes the function used in all configurations, while older longterm
releases so far don't seem to have a backport of 777c6e0dae.

The fix for the warning is trivial: move the unused function back
into the #ifdef section where it was before.
