vold: fix failing to format zero-ed out SD card
sgdisk --android-dump fails with error code 8 when there is no partition
table. Don't stop us from creating a new partition table.
Can be reproduced with
1. adb shell sm set-virtual-disk true
2. Format from UI
3. Observe fake "success" message with SD still unformatted
