virtio/vsock: use 'target' in notify_poll_in callback
This callback controls setting of POLLIN, POLLRDNORM output bits of poll() syscall, but in some cases, it is incorrectly to set it, when socket has at least 1 bytes of available data. Use 'target' which is already exists. Signed-off-by: Arseniy Krasnov <AVKrasnov@sberdevices.ru> Reviewed-by: Stefano Garzarella <sgarzare@redhat.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
