CVE-2026-98325

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

wifi: mac80211: set up the TX info early to fix failure paths

The previous commit 2c51457d930f ("wifi: mac80211: free ack status frame on TX header build failure") cleaned up the leak, but still left the code a bit messy and the failed SKB didn't get reported to userspace.

Fix this up by initialising skb->cb[] earlier, which allows using ieee80211 free txskb() and therefore reports it for the failure in ieee80211 build hdr(), and unifies the ieee80211 skb resize() failure path with it.
