fix memory leak when VT-i domain is created.
When domain is created, xend sets max vcpu before domain setup.
So alloc_vcpu_struct() think the domain is normal domU, not domVTI.
And next xend set the domain as domVTI. so the memory is allocated for
domU won't be freed.
PATCHNAME: dom_vti_memory_leak
