net: ethtool: remove error check for legacy setting transceiver type
Commit 9cab88726929605 ("net: ethtool: Add back transceiver type")
restores the transceiver type to struct ethtool_link_settings and
convert_link_ksettings_to_legacy_settings() but forgets to remove the
error check for the same in convert_legacy_settings_to_link_ksettings().
This prevents older versions of ethtool to change link settings.
# ethtool --version
ethtool version 3.16
# ethtool -s eth0 autoneg on speed 100 duplex full
Cannot set new settings: Invalid argument
not setting speed
not setting duplex
not setting autoneg
While newer versions of ethtool works.
# ethtool --version
ethtool version 4.10
# ethtool -s eth0 autoneg on speed 100 duplex full
[ 57.703268] sh-eth ee700000.ethernet eth0: Link is Down
[ 59.618227] sh-eth ee700000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx
