Prevent metadata corruption in the race conditions between
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().
