net: ethtool: require drivers to set supported_coalesce_params

Browse Source 
Now that all in-tree drivers have been updated we can
make the supported_coalesce_params mandatory.

To save debugging time in case some driver was missed
(or is out of tree) add a warning when netdev is registered
with set_coalesce but without supported_coalesce_params.
