This reverts 322cbc38 "Import mal-formed
csv files gracefully." (code now moved to a different location) which
was a workaround for a specific situation that breaks things with other
documents.

With the rework of CSV import for 3.6 the import of the one failing
document https://bugzilla.novell.com/attachment.cgi?id=294589 from
https://bugzilla.novell.com/show_bug.cgi?id=507322 works almost fine
without this workaround, with one difference in row 1805 where data is
completely broken and parts of two rows end up in one cell P1805. That
row wasn't correct with the workaround either, see also cell P1805 in
earlier versions.

As a result now without that workaround there is one data row less for
the broken document but correct data for correct documents.
