vhost-user-test failure

[Richard Henderson]

Seen on my ubuntu 22.04 laptop:

 86/591 qemu:qtest+qtest-i386 / qtest-i386/qos-test                               ERROR

The failure appears to be timeout related, so it's not consistent, but some of the error 
messages embedded in that block suggest the test never really got started correctly?
