Shuhei Matsumoto ed45352564 dix: Return DIF error information at verification for separate metadata payload 
For separate metadata payload, Introduce a struct to collect DIF error
information and pass the reference to the struct to bit-flip error injection
and verification.

This change will make logging of DIF error and comparison between
injection and verification possible for separate metadata payload.

Merging this patch to the previous is possible but add this as a separate patch
to reduce the patch size.
