userfaultfd: convert copy_huge_page_from_user() to copy_folio_from_user()

Replace copy_huge_page_from_user() with copy_folio_from_user(). 
copy_folio_from_user() does the same as copy_huge_page_from_user(), but
takes in a folio instead of a page.

Convert page_kaddr to kaddr in copy_folio_from_user() to do indenting
cleanup.
