Right. In fact, I've just tried to enable the tests (re)introduced by
8dcb404bff6d9147765d7dd3e9c8493372186420 one by one and:

- with only one of them enabled, whichever one it is, things seems fine
- with vhost_user_test_setup_reconnect and 
  vhost_user_test_setup_connect_fail enabled (in this order) things
  fail
- with vhost_user_test_setup_connect_fail and 
  vhost_user_test_setup_flags_mismatch enabled (in this order) things 
  fail
- with vhost_user_test_setup_reconnect and 
  vhost_user_test_setup_flags_mismatch enabled (in this order) things 
  fail

Even if I keep vhost_user_test_setup_reconnect and
vhost_user_test_setup_connect_fail enabled, but change the order (i.e.,
I move the qos_add_test for connect-fail before the one for reconnect,
things also fail.

I haven't tried other combinations, so far...

I'll try it. I know it fails on master (at least two days ago's
master). I'll apply the series and re-test.
