PM / devfreq: Set scaling_max_freq to max on OPP notifier error
[ Upstream commit e7cc792d00049c874010b398a27c3cc7bc8fef34 ]
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.
