    pam: fix loop in Smartcard authentication
    
    If 'try_cert_auth' or 'require_cert_auth' options are used and a wrong
    PIN is entered the PAM responder might end in an endless loop. This
    patch uses a flag to avoid the loop and makes sure that during
    authentication the error code causing the loop is not returned.
