EAP-TTLS peer: Fix user input during implicit identity request

Browse Source 
Special processing is needed to handle EAP user request for
identity or password at the beginning of Phase 2 when the implicit
identity request is used. data->pending_phase2_req needs to be set
to an empty buffer in that case to avoid re-processing the previous
part of TLS negotiation when the user enters the needed information.
