With the "inversion" of VCPUOP handling, processing arch-specific ones
first, the forwarding of this sub-op from the (common) compat handler to
(common) non-compat one did no longer have the intended effect. It now
needs forwarding between the arch-specific handlers.
Fixes: 8a96c0ea7999 ("xen: move do_vcpu_op() to arch specific code")
