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