Untested patch for trivial memory leak in update-game-score.c

[Adam Richter]

Hi, everyone.

Attached is a patch to update-games-score.c for trivial memory leaks
found by cppcheck.  In the hopes of expediting integration, I hereby
release my interest in this patch into the public domain.

As far as I can tell, update-game-score.c is not compiled when I build
emacs, so the purpose of this patch might mostly be to clean up
cppcheck output, but I did compile my modified version of the file
manually, and gcc -Wall had no complaints, although gcc -Wextra
complained about some signed/unsigned comparisons and unlock_file()
ignoring its filename parameter.

Thanks in advance for considering this patch.

Adam
