If this word is not supported, the word shall be cleared to zero. (This text also exists in really old ACS standards, e.g. ACS-3.) Additionally, move the macro to the other ATA_ID_FEATURE_SUPP macros (which already have this check), thus making it more likely that the next ATA_ID_FEATURE_SUPP macro that is added will include this check.
