Stefan Hajnoczi c0f79698ed libqos: implement VIRTIO 1.0 FEATURES_OK step ... Device initialization has an extra step in VIRTIO 1.0. The FEATURES_OK status bit is set to indicate that feature negotiation has completed. The driver then reads the status register again to check that the device agrees with the final features. Implement this step as part of qvirtio_set_features() instead of introducing a separate function. This way all existing code works without modifications. The check in qvirtio_set_driver_ok() needs to be updated because FEATURES_OK will be set for VIRTIO 1.0 devices.
