[PATCH] worktree: initialize return value for submodule_uses_worktrees

[Stefan Beller <sbeller@google.com>]

When the worktrees directory is empty, the `ret` will be returned
uninitialized. Fix it by initializing the value.

This goes on top of 1a248cf (origin/sb/submodule-embed-gitdir);
ideally to be squashed, but as it is in next already, as a separate
patch.

Thanks,
Stefan
