[Qemu-block] [PATCH v2 1/3] iotests: Make nested read in 072 and 089 read-only

[Max Reitz]

iotests 072 and 089 create a nested qcow2-in-qcow2 image. This should be
opened read-only, for one because it is indeed read only, and also
because writing to it would probably turn out bad (the outer qcow2 image
cannot grow on demand, so no clusters can be allocated for the inner
one).
