During live migration, the destination TD are initialized via importing
states from the source. So some TD-scope initialization work (e.g.
TDH.MNG.INIT) shouldn't be performed on the destination TD, and some
initialization work should be performed after the TD states are
imported. Add a flag to indicate to KVM to do post-initialization of the
TD after the migration is done.
