[PATCH V5 18/20] Fix generic/459 to work with 64k block size

With 64k block size, 200MiB disk space is not sufficient to create an
XFS filesystem. Hence this commit increases the size of the
overprovisioned dm-thin device to 300MiB. The commit also increases the
other associated disk sizes (original physical size and new physical
size) appropriately.
