If there is still some inflight IO which prevents
vhost_session_stop_done(), stop_poller can try
within 4 seconds, and then call vhost_session_stop_done
with -ETIMEDOUT.
This can avoid endless blocking in ctrl pthread if there
is no response from vhost session or its backend bdev.
Then spdk vhost target can still serve all other vhost
devices and operations besides the error one.
