为什么卡券现有库存的数量quantity的值比卡券全部库存total_quantity的值大
调取的接口是：ttps://api.weixin.qq.com/card/get?access_token=TOKEN
返回值是："sku":{"quantity":1660,"total_quantity":1090}

然而查询查询导入code数目接口调取接口：http://api.weixin.qq.com/card/code/getdepositcount?access_token=ACCESS_TOKEN
返回的值是：{"code":200,"msg":"ok","data":{"errcode":0,"errmsg":"ok","count":1810}};
