WFS: when we don't understand the schema, don't use the field width and precision
|Reported by:||Even Rouault||Owned by:||Even Rouault|
When the GML XSD parser fails to understand the schema, we fallback to issuing a GetFeature with MAXFEATURES=1 and let the GML driver build the .gfs from that. The GFS building also compute a field width and precision, but it is dangerous to use that for the whole WFS layer when computed only on a tiny extract. Better to ignore field width and precision in the WFS driver in that case.
