wifi: mt76: mt7996: fix mt7996_mcu_all_sta_info_event struct packing
The internal struct and union inside mt7996_mcu_all_sta_info_event is
marked as being aligned, which conflicts with it being unaligned
within that structure:
drivers/net/wireless/mediatek/mt76/mt7996/mcu.h:165:2: error: field within 'struct mt7996_mcu_all_sta_info_event' is less aligned than 'union mt7996_mcu_all_sta_info_event::(anonymous at ../drivers/net/wireless/mediatek/mt76/mt7996/mcu.h:165:2)' and is usually due to 'struct mt7996_mcu_all_sta_info_event' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access]
Mark all three as being packed as well to ensure byte packing for
the entire thing.
