    gnutls: Fix check for certain handshake failure conditions
    
    It seems we have no tests to see if these errors work or not, because
    the code is comparing a GTlsConnectionBaseStatus code to a GnuTLS error
    code. It has been broken since 0e94c20acdc524e82c19eb95884887b74852326d.
    The code previously used "status" as the name for a GnuTLS error code,
    then changed it to be a GTlsConnectionBaseStatus in that commit. Alas, I
    should have used a different intermediary name instead, which would have
    caught this as a compiler error.
    
    Getting the tests to return particular errors is likely impractical.
    Let's just fix this and move on.
