[Stefan Behrens]

This test failed for me with output from 'btrfs balance':
     QA output created by 003
    +Done, had to relocate 4 out of 4 chunks
    +Done, had to relocate 5 out of 5 chunks
     Silence is golden

It'd be better to redirect to $seqres.full; that way when it fails,
you'll have something to look at with more info than /dev/null contains :)

You'd need just a little prep work there to rm -f $seqres.full at the beginning
of the test so it doesn't grow forever.
