lguest: per-cpu run guest
This patch makes the run_guest() routine use the lg_cpu struct. This is required since in a smp guest environment, there's no more the notion of "running the guest", but rather, it is "running the vcpu" Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
