net: hns: fix wrong display of "Advertised link modes"

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

-----------------------------

The "Advertised link modes" always shows "1000baseT/Full", because
the driver only assigned this value.

Function ethtool_convert_link_mode_to_legacy_u32() should be called
after function phy_ethtool_ksettings_get() to get the current value
of the phy.
