ethtool: Add lanes parameter for ETHTOOL_LINK_MODE_10000baseR_FEC_BIT

Lanes field is missing for ETHTOOL_LINK_MODE_10000baseR_FEC_BIT
link mode and it causes a failure when trying to set
'speed 10000 lanes 1' on Spectrum-2 machines when autoneg is set to on.

Add the lanes parameter for ETHTOOL_LINK_MODE_10000baseR_FEC_BIT
link mode.
