[PATCH v3] btrfs/172,206: call _log_writes_cleanup in _cleanup

[Su Yue <glass.su@suse.com>]

From: Su Yue <glass.su@suse.com>

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.
