ACPI: thermal: Fix acpi_thermal_unregister_thermal_zone() cleanup
The acpi_thermal_unregister_thermal_zone() is paired with
acpi_thermal_register_thermal_zone() so it should mirror it. It should
clean up all the resources that the register function allocated and
leave the stuff that was allocated elsewhere.
Unfortunately, it doesn't call thermal_zone_device_disable(). Also it
calls kfree(tz->trip_table) when it shouldn't. That was allocated in
acpi_thermal_add(). Putting the kfree() here leads to a double free
in the acpi_thermal_add() clean up function.
Likewise, the acpi_thermal_remove() should mirror acpi_thermal_add() so
it should have an explicit kfree(tz->trip_table) as well.
Fixes: ec23c1c462de ("ACPI: thermal: Use trip point table to register thermal zones")
