Since at least commit 6b8f1020540c27246277377aa2c3331ad2bfb160 ("virtio: move host_features") the ->get_features() function has been called with host_features as an argument.
Some devices manually add host_features in ->get_features() although the features argument already contains host_features. Make all devices consistent by dropping the unnecessary code.
