x86/mm: use pagetable_free()
The kernel's memory management subsystem provides a dedicated interface,
pagetable_free(), for freeing page table pages. Updates two call sites to
use pagetable_free() instead of the lower-level __free_page() or
free_pages(). This improves code consistency and clarity, and ensures the
correct freeing mechanism is used.
