[PATCH net-next 09/20] net: hns3: Fix a loop index error of tqp statistics query

[Peng Li]

From: Jian Shen <shenjia...@huawei.com>

An error loop index was used while querying statistics data
of tqps, which may cause call trace.

Fixes: 496d03e960ae ("net: hns3: Add Ethtool support to HNS3 driver")
