Correct panic caused by attaching both Xen PV and HyperV virtualization

aware drivers on Xen hypervisors that advertise support for some
HyperV features.

x86/xen/hvm.c:
	When running in HVM mode on a Xen hypervisor, set vm_guest
	to VM_GUEST_XEN so other virtualization aware components in
	the FreeBSD kernel can detect this mode is active.

dev/hyperv/vmbus/hv_hv.c:
	Use vm_guest to ignore Xen's HyperV emulation when Xen is
	detected and Xen PV drivers are active.
