Subject: [PATCH] wifi: brcmfmac: Fix allocation size

From: "Alexey V. Vissarionov" <[email-masked]>
Date: Tue, 17 Jan 2023 13:45:08 +0300

The "pkt" is a pointer to struct sk_buff, so it's just 4 or 8
bytes, while the structure itself is much bigger.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: bbd1f932e7c45ef1 ("brcmfmac: cleanup ampdu-rx host reorder code")
