[PULL 08/19] tests/iotests: be a little more forgiving on the size test

[Alex Bennée]

At least on ZFS this was failing as 512 was less than or equal to 512.
I suspect the reason is additional compression done by ZFS and however
qemu-img gets the actual size.

Loosen the criteria to make sure after is not bigger than before and
also dump the values in the report.
