====================
net: ethtool: make sure __ethtool_get_link_ksettings() is ops-locked

This is prep for the series which will make most of the ethtool ops
run without rtnl_lock. The AI bots surfaced a number of callers of
__ethtool_get_link_ksettings() which need fixing, so I decided to
send that as a smaller prep-series. Each driver changed separately
for ease of review.
