For any recent kernel, there is a chance that btrfs/057 reports false
errors.
The false error would look like:
btrfs/057 4s ... - output mismatch (see /home/adam/xfstests-dev/results//btrfs/057.out.bad)
--- tests/btrfs/057.out 2017-08-21 09:25:33.166666666 +0800

This is related to the fact that "btrfs subvolume sync" (or
vanilla sync) will not ensure orphan (unlinked but still exist) files to
be removed.
In fact, for that false error case, if inspecting the fs after umount,
its qgroup number is correct and btrfs check won't report qgroup error.
To fix the false alerts, just skip any manual qgroup number comparison,
and let fsck done after the test case to detect problem.
This also elimiate the necessary of using specified mount and mkfs
option, allowing us to improve coverage.
