    [hotfix] [table] Fix IndexOutOfBoundsException in DataStreamSortRule.

    ## What is the purpose of the change
    
    Fixes an `IndexOutOfBoundsException` in `DataStreamSortRule` if a plan contains a sort
operator without sorting fields (just LIMIT / FETCH).
    
    ## Brief change log
    
    * Check number of sort fields before checking type of first field.
    
    ## Verifying this change
    
    Not covered by tests. `ORDER BY` without sorting fields are not supported cannot be translated.
This change just prevents an exception but does not enable the feature.
