PM / devfreq: Set scaling_max_freq to max on OPP notifier error
The devfreq_notifier_call functions will update scaling_min_freq and scaling_max_freq when the OPP table is updated. If fetching the maximum frequency fails then scaling_max_freq remains set to zero which is confusing. Set to ULONG_MAX instead so we don't need special handling for this case in other places.
