virtio-ccw/migration: Migrate config vector for virtio devices
virtio_ccw_{save|load}_config are missing code to save and restore a vdev's
config_vector value. This causes some virtio devices to become disabled
following a migration.
This patch fixes a bug whereby the qmp/hmp balloon command (virsh setmem)
silently fails to update the guest's available memory because the device was not
properly migrated.
This will break compatibility, but vmstate_s390_cpu was bumped from
version 2 to version 4 between v2.3.0 and v2.4.0 without a compat
handler. Furthermore, there is no production environment yet so
migration is fenced anyway between any relevant version of 2.3 and 2.4.
