[PATCH 6.19 313/844] wifi: rtw89: pci: validate release report content before using for RTL8922DE

[Sasha Levin]

From: Ping-Ke Shih <pkshih@xxxxxxxxxxx>

[ Upstream commit 5f93d611b33a05bd03d6843c8efe8cb6a1992620 ]

The commit 957eda596c76
("wifi: rtw89: pci: validate sequence number of TX release report")
does validation on existing chips, which somehow a release report of SKB
becomes malformed. As no clear cause found, add rules ahead for RTL8922DE
to avoid crash if it happens.
