[PATCH 2/2] mm/mmu_gather: clean up the stale code comment

[Baoquan He <bhe@redhat.com>]

In commit d7f861b9c43a ("mm/mmu_gather: add __tlb_remove_folio_pages()"),
helper function __tlb_remove_folio_pages_size() was added. And based on
the helper, wrapper functions __tlb_remove_folio_pages() and
__tlb_remove_page_size() are created and used by upper level functions.

So let's update the code comment to reflect the current code about
tlb_remove_page()/tlb_remove_page_size(), etc.
