mm/khugepaged: unify pmd folio installation with map_anon_folio_pmd()
Currently we install pmd folio with map_anon_folio_pmd() in
__do_huge_pmd_anonymous_page() and do_huge_zero_wp_pmd(). While in
collapse_huge_page(), it is done with identical code except statistics
adjustment.
Unify the process with map_anon_folio_pmd() to install pmd folio. Split
it to map_anon_folio_pmd_pf() and map_anon_folio_pmd_nopf() to be used in
page fault or not respectively.
No functional change is intended.
[akpm@linux-foundation.org: remove unneeded map_anon_folio_pmd_nopf() stub, per Wei & David]
