[PATCH V2 net-next 3/6] net: hns3: optimize the code when update the tc info

[Huazhong Tan]

From: GuoJia Liao <liaoguo...@huawei.com>

When update the TC info for NIC, there are some differences
between PF and VF. Currently, four "vport->vport_id" are
used to distinguish PF or VF. So merge them into one to
improve readability and maintainability of code.
