Prevent infinite recursion relating to limit_to_extruder

Browse source 
With limit_to_extruder, we always try to get the value of a setting from
an extruder. However, if the setting is not settable_per_extruder we
bypass the extruder and go directly to the global stack. This would
cause an infinite recursion.
