Pavel Butsykin 55289fb036 virtio-serial: add enable_backend callback ... We should guarantee that RAM will not be modified while VM has a stopped state, otherwise it can lead to negative consequences during post-copy migration. In RUN_STATE_FINISH_MIGRATE step, it's expected that RAM on source side will not be modified as this could lead to non-consistent vm state on the destination side. Also RAM access during postcopy-ram migration with enabled release-ram capability can lead to sad consequences. Let's add enable_backend() callback to avoid undesirable virtioqueue changes in the guest memory.
