tools: nv_data-md5: switch to Linux code style

This contains no functional changes.

The commented out code if any has also been preserved as it
could be relevant to the understanding of the code.

It will be kept until we understand why the code has been
commented. In that case we either need to remove it completely
or to replace it by a comment explaining why not having that
code was necessary.
