[v3,15/21] tests/qtest: use qos_printf instead of g_test_message

Commit Message

Alex Bennée July 26, 2022, 7:21 p.m. UTC

The vhost-user tests respawn qos-test as a standalone process. As a
result the gtester framework squashes all messages coming out of it
which make it hard to debug. As the test does not care about asserting
certain messages just convert the tests to use the direct qos_printf.
