Subject: [PATCH] mt76: connac: fix mt76_connac_gtk_rekey_tlv usage
Git-commit: d741abeafa47a7331cd4fe526e44db4ad3da0f62
Patch-mainline: v5.16-rc1
References: git-fixes stable-5.14.19

The mistaken structure is introduced since we added the GTK rekey offload
to mt7663. The patch fixes mt76_connac_gtk_rekey_tlv structure according
to the MT7663 and MT7921 firmware we have submitted into
linux-firmware.git.

Fixes: b47e21e75c80 ("mt76: mt7615: add gtk rekey offload support")
