Xen devel - Jan 2007 - [Xen-ia64-devel][PATCH] Fix Xen crash when creating VTI in some machines.

Xend will do a hypercall to destory domain when creating VTI guest fail.
If "is_vti" 

not be set at this point, HV will call relinquish_vcpu_resource() which
belong

to domU. It may try to free a NULL pointer, so dom0 crash. 

This patch fix it.
