WPS: Fix failure path to allow WSC_NACK and EAP-Failure to be exchanged

Browse source 
Commit c7a67a7719 forced disconnection
when wpas_clear_wps() is called. Call this function from a registered
timeout when processing a failure event in order to allow the WPS
handshake to be completed with WSC_NACK and EAP-Failure.
