When start quorum driver with 2 different sized images, we get:
qemu-system-x86_64: -drive if=virtio,driver=quorum...: Could not refresh total \
sector count: Input/output error
EIO would confuse users. With this patch, the error message goes like
Children images are not in the same size
qemu-system-x86_64: -drive if=virtio,driver=quorum...: Could not refresh total \
sector count: Invalid argument
