CVE-2026-90378

wifi: mt76: mt792x: Fix memory leak in SDIO TX path

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt792x: Fix memory leak in SDIO TX path

When tx_prepare_skb() returns an error in the SDIO TX path, the
skb is not freed, leading to a memory leak. This can occur when
zero-length frames (such as WNM NULL frames) are dropped to prevent
potential hardware TX hangs.

Fix this by properly releasing the skb with ieee80211_tx_status_ext()
when tx_prepare_skb() fails.
