Fix overly conservative behavior of update_page_write_prot().
When scanning for old->young pointers, ignore immediate values
that might happen to return a valid result from find_page_index().
At worst, this caused pages to fail to be protected when they could
have been, so it was not damaging, only suboptimal.
