x86/mm: Fix gup_huge_p?d() to handle large PAT bit
gup_huge_pud() and gup_huge_pmd() cast *pud and *pmd to *pte,
and use pte_xxx() interfaces to obtain the flags and PFN.
However, the pte_xxx() interface does not handle the large
PAT bit properly for PUD/PMD.
Fix gup_huge_pud() and gup_huge_pmd() to use pud_xxx() and
pmd_xxx() interfaces according to their type.
