Remove DeviceModel::as_user_facing_str

This patch removes the unused DeviceModel::as_user_facing_str method.
The device model is only used for the argument handling.  When printing
messages for the user, we always use nitrokey::Model.  Its Display
implementation already prints the model in an appropriate format.
