RDS: don't pretend to use cpu notifiers

Browse Source 
It looks like an attempt to use CPU notifier here which was never
completed. Nobody tried to wire it up completely since 2k9. So I unwind
this code and get rid of everything not required. Oh look! 19 lines were
removed while code still does the same thing.
