mmu_notifier: pass through vma to invalidate_range and invalidate_page v2

New user of the mmu_notifier interface need to lookup vma in order to
perform the invalidation operation. Instead of redoing a vma lookup
inside the callback just pass through the vma from the call site where
it is already available.

This needs small refactoring in memory.c to call invalidate_range on
vma boundary while previously it was call once for larger range. The
overhead might be offseted by the fact that mmu_notifier listener now
work on smaller and exact range.

Changed since v1 :
  - Only passthrough the vma.
  - Commit comment.
