extruder: Don't use max_extrude_cross_section in max_extrude_only defaults
Some users increase max_extrude_cross_section to avoid issues with
some slicers. However, increasing that value also increases the
defaults for the max_extrude_only parameters which is not obvious.
Base the max_extrude_only defaults only on the configured nozzle
diameter.
