cifs: remove ->writepage

Browse Source 
->writepage is a very inefficient method to write back data, and only
used through write_cache_pages or a a fallback when no ->migrate_folio
method is present.  Now that cifs implements ->migrate_folio and
doesn't call generic_writepages, the writepage method can be removed.
