libdm: report: fix field width calculation when using dm_report_column_headings

Browse Source 
This fixes commit 0ba5f4b8e9 which moved
field recalculation (field width and sort position) from
dm_report_object to dm_report_output but it didn't handle the case when
dm_report_column_headings was used separately to report headings (before
dm_report_outpout call) and hence we ended up with intial widths for
fields in the headings.

If we're using dm_report_column_headings, we need to recalculate
fields if we haven't done so yet, the same way as we do in
dm_report_output.
