Only in one moment we need the old and requested settings together: during _ethtool_coalesce_set(). But for that we shouldn't track both states in "NMEthtoolCoalesceState". Simplify "NMEthtoolCoalesceState" to only contain one set of options. By tracking less state, the code becomes simpler, because you don't need to wonder where the old and requested state is used.
