net: ethtool: don't ignore return from driver get_fecparam method
[ Upstream commit a6d50512b4d86ecd9f5952525e454583be1c3b14 ]
If ethtool_ops->get_fecparam returns an error, pass that error on to the
user, rather than ignoring it.
Fixes: 1a5f3da20bd9 ("net: ethtool: add support for forward error correction modes")
