Bug 2047: another fix for error during search when there is no MARC::Record

This is another fix for a bug that was introduced while adding this feature.
I believe that either this patch or the one at:
http://lists.koha.org/pipermail/koha-patches/2008-May/000309.html
should be applied.

In the case that GetMarcBiblio or GetMarcStructure does not return a true value,
this returns without further processing.
