x86/xen: don't reset vcpu_info on a cancelled suspend
On a cancelled suspend the vcpu_info location does not change (it's still in the per-cpu area registered by xen_vcpu_setup()). So do not call xen_hvm_init_shared_info() which would make the kernel think its back in the shared info. With the wrong vcpu_info, events cannot be received and the domain will hang after a cancelled suspend.
