Move backend metadata adding to fragment allocation
On the first consideration[1], metadata_adder is defined as a extra byte
size for "each" fragment. However, current implementation is an element
affects to data_len. (i.e. aligned_data_size for original segment data)
We should make metadata_adder to be a fixed value against to each fragment,
otherwise the extra bytes for the fragments will have flexible length depends
on "K". It will be quite complex for backend implementation to know "How large
bytes the raw data size is", "How large bytes the backend could use as extra
bytes for each fragment".
