virt: Fix Xen PV detection when nested inside another hypervisor

Currently, when Xen PV domains are nested within a hypervisor which is
detected through CPUID (such as VMware), the detected hypervisor might
not be Xen, because we don't check for Xen until after the CPUID check.

This change moves the Xen check before CPUID checks to fix the issue,
and moves Dom0 checking to detect_vm_xen so that we keep ignoring Xen
when we are in Dom0.
