Subject: [PATCH] wifi: ath11k: Don't drop tx_status when peer cannot be found
When a station is idle for a long time, hostapd will try to send a QoS
NULL frame to the station. The skb will be added to ack_status_frame,
waiting for a completion via ieee80211_report_ack_skb().
When a peer is removed before the tx_complete arrives, the
peer will be missing. Using dev_kfree_skb_any() which goes through
mac80211 will not delete the entry from ack_status_frames. This IDR
will therefore run full after 8K request were generated for such clients.
At this point, the access point will then just stall and not allow any new
clients because idr_alloc() for ack_status_frame will fail.
ieee80211_free_txskb() on the other hand will call
ieee80211_report_ack_skb() and make sure to remove the entry from
ack_status_frame.
