xen: netfront: assume all hw features are available until backend connection setup
We need to assume that all features will be available when registering the netdev otherwise they are ommitted from the initial set of dev->wanted_features. When we connect to the backed we reduce the set as necessary due to the call to netdev_update_features() in xennet_connect().
