Every sibling NAN TLV struct in this file (cluster_id, sync_rssi, peer_rec, map_sta_rec, ...) declares its tail padding as an explicit reserved[] member instead of relying on implicit compiler padding. Make mt7925_nan_nmi_addr_tlv consistent with that convention, and give the field a name so it shows up (zeroed) in TLV dumps instead of appearing as anonymous struct padding.
