There are usually multiple crew rest beds/"personal spaces"; in such an exceptional case as a passenger dying I really can't see how it would be anything other than a trivial matter for a couple of crew to share one of the other spaces in that circumstance - or for a crew member to relax in the deceased passenger's seat for that matter.
