WPS WiFi provisioning receives encrypted ap, but empty password leading to SYSTEM_EVENT_STA_DISCONNECTED loop (IDFGH-986)

[cduvenhorst]

When running the wps example, the WPS PBC WiFi provisioning receives encrypted ap, but an empty password. This seems to lead to a SYSTEM_EVENT_STA_DISCONNECTED loop.

WPS PBC WiFi provisioning seems to be broken at least for the AVM Fritzbox 7490 router.
