cpumask: fix powernow-k8: partial revert of 2fdf66b491ac706657946442789ec644cc317e1a

Browse Source 
Impact: fix powernow-k8 when acpi=off (or other error).

There was a spurious change introduced into powernow-k8 in this patch:
so that we try to "restore" the cpus_allowed we never saved.  We revert
that file.

See lkml "[PATCH] x86/powernow: fix cpus_allowed brokage when
acpi=off" from Yinghai for the bug report.
