mm/thp: use the correct function when updating access flags

We should use pmdp_set_access_flags to update access flags.  Archs like
powerpc use extra checks(_PAGE_BUSY) when updating a hugepage PTE.  A
set_pmd_at doesn't do those checks.  We should use set_pmd_at only when
updating a none hugepage PTE.
