Unfortunately, there is not really much that can be done to work around
this race in wpa_supplicant. More complete workaround would require
driver changes and especially in the case of ndiswrapper that is not
feasible (the change would need include the NDIS driver part).

A simpler workaround would be to make the driver enforce strict order on
key configuration and packet transmission. Anyway, that would be
out-of-scope for wpa_supplicant.
