    clipboard-rdp: Don't leak mime type table when FormatDataRequest fails
    
    It is unlikely that preparing the FormatDataRequest fails. But in case
    the preparation of sending that PDU fails, don't leak the mime type
    table.
    Free the mime type table manually without the usage of an autopointer
    to preserve the existing tail call optimization, when performing the
    next mime type content request.
