I still am not sure why stock firmware works, but it appears
the reason mine is failing is that the ACK status for mgt frames
is always set to TRUE since the ath10k wmi-mgt-tx API is so
lame.  So, mac80211 does a probe, ath10k lies and says it was
acked, and mac80211 then things all is well for another few

So, I think I'll try to come up with some way to report
proper tx-status for wmi-mgt-frames in my firmware....
