staging/slicoss: Use ethtool_ops instead of module_param.

Browse Source 
ethtool_ops has attributes in sub struct ethtool_coalesce that
correspond to the parameters intagg_delay and dynamic_intagg. It is
preferable to set these properties with ethtool rather than
module_param, so create these attributes in adapter and set them using
ethtool_coalesce's rx_coalesce_usecs and rx_use_adaptive_coalesce.
