net: phy: realtek: always clear NBase-T lpa
[ Upstream commit d3eb58549842c60ed46f37da7f4da969e3d6ecd3 ]
Clear NBase-T link partner advertisement before calling
rtlgen_read_status() to avoid phy_resolve_aneg_linkmode() wrongly
setting speed and duplex.
This fixes bogus 2.5G/5G/10G link partner advertisement and thus
speed and duplex being set by phy_resolve_aneg_linkmode() due to stale
NBase-T lpa.
