As explained in an earlier commit, we're refactoring path-related functions to provide a consistent interface for computing paths into the commondir, gitdir and worktree. Refactor the "submodule" family of functions accordingly. Note that in contrast to the other `repo_*_path()` families, we have to pass in the repository as a non-constant pointer. This is because we end up calling `repo_read_gitmodules()` deep down in the callstack, which may end up modifying the repository.
