Srinivas Pandruvada a57cc2dbb3 thermal: intel: int340x: processor_thermal: Fix additional deadlock
Commit 52f04f10b900 ("thermal: intel: int340x: processor_thermal: Fix
deadlock") addressed deadlock issue during user space trip update. But it
missed a case when thermal zone device is disabled when user writes 0.

Call to thermal_zone_device_disable() also causes deadlock as it also
tries to lock tz->lock, which is already claimed by trip_point_temp_store()
in the thermal core code.

Remove call to thermal_zone_device_disable() in the function
sys_set_trip_temp(), which is called from trip_point_temp_store().
