wsc: Try using credentials

Browse Source 
We send the scan results where we obtained a PushButton target over to
device object.  If EAP-WSC transaction is successful, then the scan
results are searched to find a network/bss combination found in the
credentials obtained.  If found, the network is connected to
automatically.
