+ ath9k: fix aggregation session lockup
+
+ If an aggregation session fails, frames still end up in the driver queue
+ with IEEE80211_TX_CTL_AMPDU set.
+ This causes tx for the affected station/tid to stall, since
+ ath_tx_get_tid_subframe returning packets to send.
+
+ Fix this by clearing IEEE80211_TX_CTL_AMPDU as long as no aggregation
+ session is running.
