Subject: [PATCH net 4/7] net: hns3: fix a bug of set mac address

From: Lipeng <lipeng321@...wei.com>

HNS3 driver get mac address from NCL_config file and set the mac address
to HW. If the mac address in NCL_config is invalid, driver will set a
random mac address, and use this address.

The current code will set random mac address to HW, but will not set the
valid mac address from NCL_config file to HW. This patch fix the bug.
