[PATCH net-next 1/4] net: hns3: modify an unsuitable print when setting unknown duplex to fibre

From: Guangbin Huang <huangguangbin2@xxxxxxxxxx>

Currently, if device is in link down status and user uses
'ethtool -s' command to set speed but not specify duplex
mode, the duplex mode passed from ethtool to driver is
unknown value(255), and the fibre port will identify this
value as half duplex mode and print "only copper port
supports half duplex!". This message is confusing.

So for fibre port, only the setting duplex is half, prints
error and returns.
