Bug 23663: Only process itemtype summary if using non-xslt opac results

To test:
1 - Set OpacXSLTResultsDisplay to "" to use non-xslt view
2 - In Administration->Itemtypes define a summary for an itemtype:
    This is the summary for [245a]
3 - Perform a search on the opac that will return results with this itemtype
4 - Note "This is the summary" appears in results with the title
5 - Set OPACXSLTResultsDisplay to 'default'
6 - Refresh your search results, note the summary disappears
7 - Try search in other places and note that summary never appears
8 - Apply patch
9 - Repeat 1-7 and note nothing changed
