ANDROID: Sched: Add restricted vendor hook in update_misfit_status()

Browse Source 
Added a hook in update_misfit_status() for our vendor scheduler
logic to move the task to more capable CPU incase,
if old misfit value is not same as current misfit value.

This vendor hook was part of
commit 292f430816
(ANDROID: Sched: Add restricted vendor hooks for scheduler)

But commit 7219ca326a
(Revert "ANDROID: Sched: Add restricted vendor hooks for scheduler")
deleted above vendor hooks stating unused

Adding back above vendor hooks required for EMS.

Bug: 259900798
