As the trip temperature is already available when calling the function
handle_critical_trips(), pass it as a parameter instead of having this
function calling the ops again to retrieve the same data.

This indent cleanup belongs to patch 1/4.
Other than that,

It is not an indent cleanup, the 'int trip_temp' is added in the parameters.
