Test cases with dm_target shall call _require_scratch* before
_require_dm_target. However, three test cases generic/628, generic/629 and
btrfs/146 do not follow this rule and result in unexpected failures. The first
patch in this series fixes the failures in generic/628 and generic/629. The
second patch fixes it in btrfs/146. The last patch improves _require_dm_target
to prevent the failure in the future test cases to be added.
The failure was found with generic/628 and generic/629. I checked all existing
test cases and found btrfs/146 also has the issue.
Changes from v1:
* Changed fix approach according to comment on the list
* Added fix for btrfs/146 as the 2nd patch
* Separated improvement in _require_dm_target as the last patch

_require_dm_target

_require_scratch*
