[PATCH 01/23] wifi: mt76: mt7925: make NMI address TLV tail padding explicit

[Sean Wang <sean.wang@kernel.org>]

From: Chengwei Yu <chengwei.yu@mediatek.com>

struct mt7925_nan_nmi_addr_tlv is __packed __aligned(4). tag+len+
nmi_addr is 10 bytes, so the aligned attribute already inserts 2
bytes of implicit tail padding to round the struct up to 12 bytes;
sizeof() is unchanged by this patch.

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.
