[PATCH net 3/3] net: hns3: fix ETS bandwidth validation bug

[Huazhong Tan <tanhuazhong@huawei.com>]

From: Yonglong Liu <liuyonglong@huawei.com>

Some device only support 4 TCs, but the driver check the total
bandwidth of 8 TCs, so may cause wrong configurations write to
the hw.

This patch uses hdev->tc_max to instead HNAE3_MAX_TC to fix it.
