[freetds] Bug in ct_describe

Hi all

I had some headache with ct_fetch, returning CS_ROW_FAIL in a more or less 
random manner. My investigation had shown that ct_describe doesn't set 
the "format" member of the CS_DATAFMT struct. Therefore cs_convert returns 
CS_FAIL if it hits a column of a type which can be modified by a CS_FMT_* 
parameter and the value of "format" is no a valid CS_FMT_*.

Setting it to CS_FMT_UNUSED in my code all the time fixed the problem and 
Sybase' ctlib seem to do the same.
