[CARBONDATA-2150] Unwanted updatetable status files are being generated for
the delete operation where no records are deleted
**Problem:** Unwanted updatetable status files are being generated for the
delete operation where no records are deleted
**Analysis:**when the filter value for delete operation is less than the
maximum value in that column, then getsplits() will return the block and hence
in delete logic, it was creating update table status file even though delete
operation was not done.
