When mac80211 debug is enabled, the trace below appears:
[60744.340037] wlan0: Rx A-MPDU request on aa:bb:cc:97:60:24 tid 0 result -524
This imply that ___ieee80211_start_rx_ba_session will prematurely exit
and frame reordering won't be enabled.
Fixes: e5da5fbd77411 ("staging: wfx: fix CCMP/TKIP replay protection")
