tests/functional: fix race in virtio balloon test
There are two race conditions in the recently added virtio balloon
test
* The /dev/vda device node is not ready
* The virtio-balloon driver has not issued the first stats refresh
To fix the former, monitor dmesg for a line about 'vda'.
To fix the latter, retry the stats query until seeing fresh data.
Adding 'quiet' to the kernel command line reduces serial output
which otherwise slows boot, making it less likely to hit the former
race too.
