Fix pointer overwrite in mt7921s_tx_prepare_skb and
mt7663_usb_sdio_tx_prepare_skb routines since in
commit '2a9e9857473b ("mt76: fix possible pktid leak")
mt76_tx_status_skb_add() has been moved out of
mt7921s_write_txwi()/mt7663_usb_sdio_write_txwi() overwriting
hw key pointer in ieee80211_tx_info structure. Fix the issue saving
key pointer before running mt76_tx_status_skb_add().
