net: hns: fix port not available after testing loopback

Browse source

After running command "ethtool -t eth0", eth0 can not be connected to
network. It is caused by the changing the inner loopback register and
this register cannot be changed when hns connected to network. The
routine of setting this register needs to be removed and using promisc
mode to let the packet looped back pass by dsaf mode.
