From: Liang Li <[email protected]> Because of commit 11808bb0c422, which remove some condition checks of 'f->ops->writev_buffer', 'qemu_put_qemu_file' should be enhanced to clear the 'f_src->iovcnt', or 'f_src->iovcnt' may exceed the MAX_IOV_SIZE which will break live migration. This should be fixed.
