[Libreoffice] [PATCH] Refactor to make cppcheck happy

From the 'easy hacks' page it seemed that getting rid of warnings and flags
by tools like cppcheck was a goal.

Attached is a small patch that does nothing except eliminate one cppcheck
warning.  It is contributed under the LGPL3+.

As I said, it does nothing different and, depending on the compiler, it
could even be less efficient.  It does however make cppcheck happy.

Is this kind of thing useful?
