Because block group tree requires require no-holes feature,
_log_writes_mkfs "-O ^no-holes" fails when "-O block-group-tree" is
given in MKFS_OPTION.
Without explicit _log_writes_cleanup, the two tests fail with
logwrites-test device left. And all next tests will fail due to
SCRATCH DEVICE EBUSY.

Fix it by overriding _cleanup to call _log_writes_cleanup.

Currently we need to copy the code in default _cleanup into new _cleanup()
function, if you need a override, e.g.


Sorry for the late reply, I was working on other things with headache. I saw the cleanup thing you mentioned in v1 thread. v3 was sent. Thanks.
