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