nfs: fix another case of NULL/IS_ERR confusion wrt folio pointers
Dan has been improving on the smatch error pointer checks, and pointed
at another case where the __filemap_get_folio() conversion to error
pointers had been overlooked. This time because it was hidden behind
the filemap_grab_folio() helper function that is a wrapper around it.
