Bug 27011: Remove unused $name variable

The variable is no longer used in the template, it has been removed by:

  commit 76eb3a0549efe4c1f1557071a6cb4b33d4bd3e4d
  Bug 18789: (follow-up) Pass a Koha::Patron object from returns.pl

-            <td>[% name %]</td>
+            <td>[% INCLUDE 'patron-title.inc' patron=patron %]</td>

We can simply remove the $name variable from the controller script.

Test Plan:
1. Check out a book
2. Check in a book
3. Note what happens
4. Apply patch
5. Repeat step 1-2
6. Note that it doesn't break and everything still works
