Bug 41128: Only use data rating if it's available

This patch prevents span elements being filled with "undefined"
which are then shown to screen readers and print output.

Test plan:
0. Apply the patch
1. Enable the following system preference: OpacStarRatings (results,
   details, and patron).
2. Check out an item to a user you can log in as (e.g. koha user)
3. Go to /cgi-bin/koha/opac-user.pl in the OPAC
4. Click "Print" on the toolbar above the summary table
5. Note that 5 occurrences of "undefined" do not appear next to the
   title in the print output
