From: Philippe Mathieu-Daudé <philmd@linaro.org> The VirtIOPCIProxy::ignore_backend_features boolean was only set in the hw_compat_2_7[] array, via the 'x-ignore-backend-features=on' property. We removed all machines using that array, lets remove that property, simplify by only using the default version.
