Settings: fix led pulsespeedoff disable behaviour

Keep led pulsespeedoff disabled if pulsespeedon is disabled.  This ensures that pulsespeedoff stays disabled if onOffChangeable was set to false.  Fixes problem where charged led pulsespeed off looks to be configurable in the ui and thereby creating user confusion.
