[mutter] session: Don't set XSMP restart

[Colin Walters <walters src gnome org>]

commit 3cd0e86bddb088aa0632f2593e77b4a6dc59ae43

    session: Don't set XSMP restart
    
    This made sense back in the day of stateless window managers,
    but gnome-shell isn't.  gnome-session will handle gnome-shell
    crashing, since it's a required component.
