PM / devfreq: Fix devfreq_notifier_call returning errno

[ Upstream commit e876e710ede23f670494331e062d643928e4142a ]

Notifier callbacks shouldn't return negative errno but one of the
NOTIFY_OK/DONE/BAD values.

The OPP core will ignore return values from notifiers but returning a
value that matches NOTIFY_STOP_MASK will stop the notification chain.

Fix by always returning NOTIFY_OK.
