This function iterates over all snapshots of a qcow2 file in order to expand all zero clusters, but it does not validate the snapshots' L1 tables first. We now have a function to take care of this, so let's use it. We can also take the opportunity to replace the sector-based bdrv_read() with bdrv_pread().
