vhost-user-test: do not hang if chardev creation failed
Before the chardev name fix, the following error may happen: "attempt to add duplicate property 'chr-test' to object (type 'container')", due to races. Sadly, error_vprintf() uses g_test_message(), so you have to use read the cryptic --debug-log to see it. Later, it would make sense to use g_critical() instead, and catch errors with g_test_expect_message() (in glib 2.34).
