We have a race between the nbd server and the client both trying
to report errors at once which can make the test sometimes fail
if the output lines swap order under load. Break the race by
collecting server messages into a file and then replaying that
at the end of the test.

An alternative solution might be to silence the message from the
server by default, and output it only when -v was passed
