nfp: ethtool: add extended ack report messages
Add descriptive error messages to common ethtool failures to be more
user friendly.
Update `nfp_net_coalesce_para_check` to only check one argument, which
facilitates unique error messages.
Additionally, three error codes are updated to `EOPNOTSUPP` to reflect
that these operations are not supported.
