xgbe: let core reject the unsupported coalescing parameters

Browse source 
Set ethtool_ops->supported_coalesce_params to let
the core reject unsupported coalescing parameters.

This driver correctly rejects all unsupported parameters.
We are only losing the error print.

v3: adjust commit message for new error code and member name
