mm/page_idle.c: remove redundant mmu notifier in aging code

Browse Source 
Now we have mmu_notifier_clear_young immediately follows
pmdp_clear_young_notify which internally calls mmu_notifier_clear_young,
this is redundant.  change it with non-notify variant and keep consistent
with ptep aging code.
