mm: simplify follow_invalidate_pte()
The only user (DAX) of range and pmdpp parameters of
follow_invalidate_pte() is gone, it is safe to remove them and make it
static to simlify the code. This is revertant of the following commits:
097963959594 ("mm: add follow_pte_pmd()")
a4d1a8852513 ("dax: update to new mmu_notifier semantic")
There is only one caller of the follow_invalidate_pte(). So just fold it
into follow_pte() and remove it.
