wifi: iwlwifi: cancel session protection only if there is one
mac80211 might (due to an unavoidable race) cancel a ROC that has already
expired. In that case the driver should not send the session protection
cmd to cancel the ROC.
When session protection is supported, the te_data::id field is reused
to save the configuration id. Check it before sending the cmd.
