e1000: Convert v3 fields to subsection 

A bunch of new TSO fields were introduced by d62644b4 and this bumped
the VMState version; however it's easier for those trying to keep
backwards migration compatibility if these fields are added in a
subsection instead.

Move the new fields to a subsection.

Since this was added after 2.11, this change will only affect
compatbility with 2.12-rc0.
