mac80211: Complete ampdu work schedule during session tear down
Commit 7a7c0a6438b8 ("mac80211: fix TX aggregation start/stop callback race") added a cancellation of the ampdu work after the loop that stopped the Tx and Rx BA sessions. However, in some cases, e.g., during HW reconfig, the low level driver might call mac80211 APIs to complete the stopping of the BA sessions, which would queue the ampdu work to handle the actual completion. This work needs to be performed as otherwise mac80211 data structures would not be properly synced. Fix this by checking if BA session STOP_CB bit is set after the BA session cancellation and properly clean the session.
