DDF: write_init_super_ddf: don't zero superblocks for subarrays

commit d682f344 inserted this call to "Kill" in write_init_super_ddf:

    "Matching the functionality already in super0 and super1, when
    we first create a container, remove any other recognisable metadata to
    ensure it doesn't cause confusion."

But we should do this only at first container creation, not when
subarrays are created later.
