thermal: core: Fix disabled trip point check in handle_thermal_trip()thermal-6.6-rc2
Commit bc840ea5f9a9 ("thermal: core: Do not handle trip points with invalid temperature") added a check for invalid temperature to the disabled trip point check in handle_thermal_trip(), but that check was added at a point when the trip structure has not been initialized yet. This may cause handle_thermal_trip() to skip a valid trip point in some cases, so fix it by moving the check to a suitable place, after __thermal_zone_get_trip() has been called to populate the trip structure.
