intel_idle: Revert change of auto_demotion_disable_flags for Nehalem
Commit b66b8b9a4a
('intel-idle: convert
to x86_cpu_id auto probing') added a distinction between Nehalem and
Westemere processors and changed auto_demotion_disable_flags for the
former to 0. This was not explained in the commit message, so change
it back.
