Turn InitService::doShutdown into a NO_RETURN

    There are a few places outside of initservice where Hostboot
    shutdown needs to be called.  Currently the doShutdown returns
    so each of these places have a while(1); style loop.  In the
    case of start_payload, their implementation of this loop was
    incorrect and causes us to take longer than desired to actually
    shutdown.

    I have changed doShutdown into a NO_RETURN function that keeps
    the correct loop done in a common way.

    See defect SW183911 for more background.
