x86/mm: Fix __split_large_page() to handle large PAT bit
__split_large_page() is called from __change_page_attr() to change
the mapping attribute by splitting a given large page into smaller
pages. This function uses pte_pfn() and pte_pgprot() for PUD/PMD,
which do not handle the large PAT bit properly.
Fix __split_large_page() by using the corresponding pud/pmd pfn/
pgprot interfaces.
Also remove '#ifdef CONFIG_X86_64', which is not necessary.
