WPS: Use shorter authentication timeout during no-SelReg iteration

Browse source 
When iterating through WPS APs that do not advertise Selected Registrar
TRUE, limit the authentication timeout to 10 seconds instead of the full
70 second value used with IEEE 802.1X/EAP/WPS in general. This helps
speed up AP iteration for cases where a selected AP misbehaves and does
not reply to EAP exchanges. This should not really be needed, but there
seems to be deployed APs that do not implement WPS correctly and with
such APs in the radio range, this extra timeout can speed up the
iteration to allow the correct AP to be found before the WPS operation
times out.
