wifi: mac80211: Fix ack frame idr leak when mesh has no route
[ Upstream commit 39e7b5de9853bd92ddbfa4b14165babacd7da0ba ]
When trying to transmit an data frame with tx_status to a destination
that have no route in the mesh, then it is dropped without recrediting
the ack_status_frames idr.
Once it is exhausted, wpa_supplicant starts failing to do SAE with
NL80211_CMD_FRAME and logs "nl80211: Frame command failed".
Use ieee80211_free_txskb() instead of kfree_skb() to fix it.
