commit af674d4e20a82c2a98767b837072d7093c70b1cf

    Fix d2i_SSL_SESSION for DTLS1_BAD_VER
    
    Some Cisco appliances use a pre-standard version number for DTLS. We support
    this as DTLS1_BAD_VER within the code.
    
    This change fixes d2i_SSL_SESSION for that DTLS version.
    
    Based on an original patch by David Woodhouse <dwmw2 at infradead.org>
    
    RT#3704
