no error column in structured error handler for xml schema validation errors

For https://bugzilla.gnome.org/show_bug.cgi?id=734363

When using xml schema validation, structured error callbacks do not get
passed a valid column number in xmlError field "int2".

$ ./xmlsaxparse colbug5.xml colbug5.xsd
colbug5.xml:3:0: Element '{urn:colbug5}bx': This element is not
expected.
Expected is ( {urn:colbug5}b ).

The schema error is reported for line 3, column 0 (= N/A).

I'd like to have the column number of the error passed in the xmlError
structure.  With this test case: line 3, column 9.
