net: hns3: fix a phy loopback fail issue 

[ Upstream commit f04bbcbf1e ]

When phy driver does not implement the set_loopback interface,
phy loopback test will return -EOPNOTSUPP, and the loopback test
will fail. So when phy driver does not implement the set_loopback
interface, don't do phy loopback test.
