The `write_idx_file()` function uses the global `the_hash_algo` variable to access the repository's hash function. To avoid global variable usage, pass the hash function from the layers above. Since `stage_tmp_packfiles()` also resides in 'pack-write.c' and calls `write_idx_file()`, update it to accept `the_hash_algo` as a parameter and pass it through to the callee. Altough the layers above could have access to the hash function internally, simply pass in `the_hash_algo`. This avoids any compatibility issues and bubbles up global variable usage to upper layers which can be eventually resolved.
