Muchun Song 0e5e64c0b0 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:

  0979639595 ("mm: add follow_pte_pmd()")
  a4d1a88525 ("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.
