So this test does lots of fallocate/truncate noise while doing aio overwrites to
try and exercise a deadlock found in ext4.  Because it runs so hard with ENOSPC
it can sometimes cause truncate to fail on btrfs.  This is ok and doesn't affect
the validity of the test, we just need to catch the output so it doesn't cause
the test to fail.  Thanks,
