Make sure map_win initialize win::win_data

Previously it is initialized by win_update_bounding_shape, so
configure_win is called when win_data == NULL and state ==
WSTATE_MAPPING, which is an invalid state for a `win` to be in.

Now map_win explicitly calls backend->prepare_win. This is not very
efficient since win_update_bounding_shape will reinit it.
