thermal/drivers/qcom/spmi-adc-tm5: Don't abort probing if a sensor is not used
adc_tm5_register_tzd() registers the thermal zone sensors for all channels of the thermal monitor. If the registration of one channel fails the function skips the processing of the remaining channels and returns an error, which results in _probe() being aborted. One of the reasons the registration could fail is that none of the thermal zones is using the channel/sensor, which hardly is a critical error (if it is an error at all). If this case is detected emit a warning and continue with processing the remaining channels.
