This is needed to allows WPS PBC session overlap detection to work with drivers that process Probe Request frames internally. This code is is run in hostapd, but the wpa_supplicant AP mode did not have call to the hostapd_probe_req_rx() function even though it registered handlers for hostapd Probe Request RX callbacks.
