Amaury Pouly 193753aa1f Introduce volume_{present,removable} and fix invalid calls in apps/
The code was trying to probe for volume presence by calling drive layer
with volume index. It is a miracle it get unnoticed so far. Introduce
proper volume probing using the vol->drive map in the disk layer.
