[Qemu-block] [PULL 03/19] qemu-iotests: redirect nbd server stdout to /dev/null

[Kevin Wolf]

From: Jeff Cody <address@hidden>

Some iotests (e.g. 174) try to filter the output of _make_test_image by
piping the stdout.  Pipe the server stdout to /dev/null, so that filter
pipe does not need to wait until process completion.
