[PATCH v1 05/16] mm/oom_kill: use MMU_NOTIFY_CLEAR in __oom_reap_task_mm()

[David Hildenbrand (Arm)]

In commit 7269f999934b ("mm/mmu_notifier: use correct mmu_notifier events
for each invalidation") we converted all MMU_NOTIFY_UNMAP to
MMU_NOTIFY_CLEAR, except the ones that actually perform munmap() or
mremap() as documented.

__oom_reap_task_mm() behaves much more like MADV_DONTNEED. So use
MMU_NOTIFY_CLEAR as well.

This is a preparation for further changes.
