[PATCH 6/8] net/hns3: delete rte unused tag

[Dongdong Liu <liudongdong3@huawei.com>]

From: Huisong Li <lihuisong@huawei.com>

The '__rte_unused' tag in the input parameter  of 'hns3_mac_stats_reset'
is redundant. This patch remove this tag. In addition, this function is
aimed to clear MAC statics. So using 'struct hns3_hw' as input parameter
is better than 'struct rte_eth_dev', and it also facilitates the call of
this function.

Fixes: 8839c5e202f3 ("net/hns3: support device stats")
