    libcli: Add debug message if fail to negoatiate SMB protocol

    Currently if the client and server can't negotiate an SMB protocol, you
    just get the followiing error on the client-side, which doesn't tell you
    much.
    ERROR(runtime): uncaught exception - (3221225667, 'The network responded
    incorrectly.')

    This patch adds a debug message to help highlight what's actually going
    wrong.
