If there is still work to do, it is not safe to assume we
can end the dirty tracking. Specifically, kvm can update the dirty
tracking log inside ram_save_block(), leaving pages still out of sync...

propagate error on failed completion (Glauber Costa)

migrate_fd_put_ready() calls qemu_savevm_state_complete(),
but the later can fail.

If it happens, re-start the vm and propagate the error up
