However, currently if\nan intermediate function fails before sending, the allocated skb is\nleaked.\n\nSpecifically, mt76_connac_mcu_sta_wed_update() and\nmt76_connac_mcu_sta_key_tlv() may fail, leading to an immediate memory\nleak in the error path.\n\nFix this by explicitly freeing the skb in these error paths.\nCommit 7c0f63fe37a5 (\"wifi: mt76: mt7996: fix memory leak on\nmt7996_mcu_sta_key_tlv error\") made a similar change.\n\nCompile tested only.
