net: hns3: fix port duplex configure error in IMP reset
[ Upstream commit 11d80f79dd9f871a52feba4bf24b5ac39f448eb7 ]
Currently, the mac port is fixed to configured as full dplex mode in
hclge_mac_init() when driver initialization or reset restore. Users may
change the mode to half duplex with ethtool, so it may cause the user
configuration dropped after reset.
To fix it, don't change the duplex mode when resetting.
