xen-netfront: Improve error handling during initialization
This fixes a crash when running out of grant refs when creating many queues across many netdevs. * If creating queues fails (i.e. there are no grant refs available), call xenbus_dev_fatal() to ensure that the xenbus device is set to the closed state. * If no queues are created, don't call xennet_disconnect_backend as netdev->real_num_tx_queues will not have been set correctly. * If setup_netfront() fails, ensure that all the queues created are cleaned up, not just those that have been set up. * If any queues were set up and an error occurs, call xennet_destroy_queues() to clean up the napi context. * If any fatal error occurs, unregister and destroy the netdev to avoid leaving around a half setup network device.
