EAP-TEAP peer: Process Crypto-Binding TLV before EAP Payload TLV

EAP-TEAP peer: Process Crypto-Binding TLV before EAP Payload TLV

When using the optimized EAP method sequence within the tunnel, crypto
binding for the previous EAP method can be performed in the same message
with the start of the next EAP method. The Crypto-Binding TLV needs to
be processed before moving to the next EAP method for IMSK to be derived
correctly, so swap the order of these processing steps.
