Subject: [PATCH net-next 2/8] net: hns3: add hns3_state_init() to do state initialization

From: Huazhong Tan <tanhuazhong@...wei.com>

To improve the readability and maintainability, add hns3_state_init() to
initialize the state, and this new function will be used to add more state
initialization in the future.
