pcache_meta_find_latest() leaves whatever it last copied into the caller’s buffer even when it returns NULL. For cache_info_init(), that meant cache->cache_info could still contain CRC-bad garbage when no valid metadata exists, leading later initialization paths to read bogus flags. Explicitly memset cache->cache_info in cache_info_init_default() so new-cache paths start from a clean slate. The default sequence number assignment becomes redundant with this reset, so it drops out.
