Subject: [PATCH] cpufreq: Unbreak build for !SMP: symlinked cpus cannot happen for !SMP

Or like that:
Either all #ifdef CONFIG_SMP related conditionals to managed cpus
should vanish or all should be covered. This one takes the latter
approach.

---
'managed_policy' is used for the non-smp case in line 941.

Make the symlink code conditional to #ifdef CONFIG_SMP as already
done at other places.
