ACPI: thermal: Fix stale comment regarding trip points

Update the comment next to acpi_thermal_get_trip_points() call site
in acpi_thermal_add() to reflect what the code does.

It has diverged from the code after changes that removed the _CRT
evaluation from acpi_thermal_get_trip_points() among other things.
