We build dm device on top of scratch dev so we require $SCRATCH_DEV
to be a valid block device in _require_dm_target(). And we need to
_require_scratch before _require_dm_target, otherwise test fails if
there's no SCRATCH_DEV defined, where it should _notrun.
+Usage: _require_block_device <dev>
So add _require_scratch_nocheck to generic/347 (we do the fs check
on thinp device), move _require_scratch before _require_dm_target in
xfs/006 and xfs/264.

Fairly trivial test to use the dm-thin infrastructure.
Right now it exhausts space in queue-on-error mode,
adds more space, does a bit more IO, then unmounts &
checks the fs.
Not sure if that's valid to test, but it works here and
demonstrates the common/dmthin helpers.
