FOP->open() and FOP->link(). Problem: crypt_open() modifies @local->format, which is used by crypt_link() to store the updated metadata string on disk. This results in metadata corruption. Fixup: Don't modify @local->format by FOP->open(). Instead modify a local copy, allocated in the low-level meta-data handler open_format_v1().
