wps: Relax the check on older config methods in case of WPS2.0 (backport v3.1)

Browse source 
Some APs incorrectly advertize newer WPS2.0 config method bits
without setting bits for the corresponding older methods. This
results in failures during 8-way handshake. Add a workaround to
relax this check so that WPS handshake can proceed.
