Since 69aba5329 (submodule: add repo_read_gitmodules) there have been two ways to load a repository's .gitmodules file: 'repo_read_gitmodules()' is used if you have a repository object you are working with or 'gitmodules_config()' if you are implicitly working with 'the_repository'. Merge the logic of these two functions to remove duplicate code. In addition, 'repo_read_gitmodules()' can segfault by passing in a NULL pointer to 'git_config_from_file()' if a repository doesn't have a worktree. Instead check for the existence of a worktree before attempting to load the .gitmodules file.
