qcow2: Fix potential qemu-img check crash on 32 bit hosts
This crash was caught with qemu-iotests test case 138.
Commit b6d36de already fixed a few 32 bit truncation bugs that could
cause qemu-img check to allocate too little memory and consequently
it would segfault. On 32 bit hosts, there is one more place that needs
to be fixed because size_t was involved in the calculation and is a
32 bit type there.
