[PATCH v4 05/17] dump: Cleanup and annotate guest memory related DumpState struct members

[Janosch Frank]

We can safely remove next_block and start as both of them aren't used
anymore due to the block iteration re-work.

Also we add comments to the remaining guest memory related struct
members and a comment on top to group them.
