[0/2] fstests: prevent dm-log-writes out of order replay issues

Here's a stab at addressing the out-of-order write issues reproduced by
generic/482 on XFS v5 filesystems. Patch 1 refactors the code to allow
for use of an arbitrary device and patch 2 fixes up generic/482 to use a
thinly provisioned replay device.

This could be factored in different ways and/or be implemented across
the other tests, but the focus here is on generic/482.
