Lu Baolu a1593c9089 x86/mm: use pagetable_free() 
commit bf9e4e30f3 upstream.

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.
