ieee80211_tx_h_check_assoc() was dropping everything else than probe requests during software scan. So the null frame with the power save bit was dropped and AP never received it. This meant that AP never buffered any frames for the station during software scan. Fix this by allowing to transmit both probe request and null frames during software scan. Tested with stlc45xx.
