f2fs: make f2fs_verify_cluster() partially large-folio-aware 



f2fs_verify_cluster() is the only remaining caller of the
non-large-folio-aware function fsverity_verify_page().   To unblock the
removal of that function, change f2fs_verify_cluster() to verify the
entire folio of each page and mark it up-to-date.

Note that this doesn't actually make f2fs_verify_cluster()
large-folio-aware, as it is still passed an array of pages.  Currently,
it's never called with large folios.
