[CPUFREQ] cpumask: avoid playing with cpus_allowed in speedstep-ich.c
Impact: don't play with current's cpumask
It's generally a very bad idea to mug some process's cpumask: it could
legitimately and reasonably be changed by root, which could break us
(if done before our code) or them (if we restore the wrong value).
We use smp_call_function_single: this had the advantage of being more
efficient, too.
