Bug 23183: Reindent cataloging.js

Bug 23183: Reindent cataloging.js

This patch makes some very minor corrections to indentation in
cataloging.js, a JavaScript file used by the bibliographic and item
records editors.

To test, apply the patch and perform a diff against master using the
'-w' flag:

git diff -w origin/master

There should be no changes reported.
