sched/walt: Remove unused sched_dynamic_ravg_window_enable tunable

Browse Source 
sched_dynamic_ravg_window_enable tunable is not currently used. If 0
is written to this tunable, the dynamic window size feature is disabled
in the kernel which results in bad performance. So remove this unused
tunable.
