[PATCH RESEND 12/13] net/hns3: fix uncleared hardware MAC statistics

[Dongdong Liu]

From: Huisong Li <lihuisong at huawei.com>

In the situation that the driver hns3 exits abnormally during packets
sending and receiving, the hardware statistics are not cleared when the
driver hns3 is reloaded. It need to be cleared during driver hns3
initialization that hardware MAC statistics.
