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.
