[PATCH net-next] mlxsw: spectrum: remove set but not used variable 'autoneg_status'

[YueHaibing]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/ethernet/mellanox/mlxsw/spectrum.c: In function 
'mlxsw_sp_port_get_link_ksettings':
drivers/net/ethernet/mellanox/mlxsw/spectrum.c:3062:5: warning:
 variable 'autoneg_status' set but not used [-Wunused-but-set-variable]

It's not used since commit 475b33cb66c9 ("mlxsw: spectrum: Remove unsupported
eth_proto_lp_advertise field in PTYS")
