xen: fix incorrect vcpu_register_vcpu_info hypercall argument
The kernel's copy of struct vcpu_register_vcpu_info was out of date,
at best causing the hypercall to fail and the guest kernel to fall
back to the old mechanism, or worse, causing random memory corruption.
[ Stable folks: applies to 2.6.23 ]
