[PATCH ath-next v2 0/2] wifi: ath11k: do not fail down transitions of the station state

[Julius Bairaktaris <julius@bairaktaris.de>]

mac80211 warns when a driver fails a down transition of the station
state, and ath11k does so while the firmware is down. Patch 2 fixes that.
Patch 1 is new: with the firmware down, a key whose removal failed stayed
in peer->keys[] although mac80211 had freed it.

I used Claude (Anthropic) to help write these patches.

Tested on an IPQ8074 AP (hw2.0 AHB, WLAN.HK.2.12-01460): the firmware was
crashed through debugfs and the station deleted at once. In 3 of 3 runs
with this series station del returned 0 with no mac80211 warning and no
key removal error, and the station re-associated. With the v1 patch alone,
one run logged "failed to remove peer key 0: -108" and "failed to clear all
peer keys for vdev 0: -108".

Changes in v2:
- New patch 1.
- Patch 2: continue the host cleanup after a failed early vdev stop and
  a failed RTS/CTS update instead of returning from them (Sashiko review
  of v1).
