lguest: make hypercalls use the vcpu struct
this patch changes do_hcall() and do_async_hcall() interfaces (and obviously their callers) to get a vcpu struct. Again, a vcpu services the hypercall, not the whole guest Signed-off-by: Glauber de Oliveira Costa <gcosta@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
