The number of blocks of the device is used to compute the device size in bdrv_getlength()/iscsi_getlength(). For MMC devices, the ReturnedLogicalBlockAddress in the READCAPACITY10 has a special meaning when it is 0. In this case it does not mean that LBA 0 is the last accessible LBA, and thus the device has 1 readable block, but instead it means that the disc is blank and there are no readable blocks. This change ensures that when the iSCSI LUN is loaded with a blank DVD-R disk or similar that bdrv_getlength() will return the correct size of the device as 0 bytes.
