Subject: [PATCH] thermal/drivers/int340x/processor_thermal: Fix warning for
 return value

Fix smatch warnings:
drivers/thermal/intel/int340x_thermal/processor_thermal_device_pci.c:258 proc_thermal_pci_probe() warn: missing error code 'ret'

Use PTR_ERR to return failure of thermal_zone_device_register().
