    Save/Restore Support: Refactor HYPERVISOR_suspend hypercall
    
    Directly using the SHUTDOWN_suspend macro as a parameter for the schedop
    hypercall causes an error in the Xen hypercall handler. Also for 
consistency,
    the SHUTDOWN_suspend param is wrapped in the sched_shutdown struct.
