[PATCH v4 2/4] thermal/core: Avoid calling ->get_trip_temp() unnecessarily

[Daniel Lezcano <daniel.lezcano@linaro.org>]

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.
