s390x/migration: add comment about floating point migration
commit 46c804def4bd ("s390x: move fpu regs into a subsection
of the vmstate") moved the fprs into a subsection and bumped
the version number. This will allow to not transfer fprs in
the future if necessary. Add a comment to mark the return true
as intentional.
