Subject: mm: don't call mark_page_accessed() in do_swap_page()

commit bf3f3bc5e734706730c12a323f9b2068052aa1f0 (mm: don't
mark_page_accessed in fault path) only remove the mark_page_accessed() in
filemap_fault().

Therefore, swap-backed pages and file-backed pages have inconsistent
behavior.  mark_page_accessed() should be removed from do_swap_page().
