iwlwifi: mvm: ignore temperature updates in the RX statistics notification
If the firmware sends spontaneous DTS notfications with the
temperature (indicated in a TLV), we can ignore the temperature we get
in the RX statistics notifications. This prevents potentially
handling the same temperature change twice. It also ignores
notifications with temperature equal to 0 that happens from time to
time.
