Subject: [PATCH] BackingFile property should be use with StorageVolume instead
of StorageAccess
BUG: 434617
When mounting an iso with `udisksctl`, first a loop device is created
`/dev/loop0` then a second device `/dev/loop0p1` is used to mount it on
a filesystem location.
Querying for StorageAccess devices sometimes only returns the `/dev/loop0p1`
device without the `/dev/loop0` device and the BackingFile property does not
work on `/dev/loop0p1`.
Solution: query for StorageVolume instead which returns all loop devices:
`/dev/loop0` and `/dev/loop1`.
Warning: Because StorageVolume returns more devices, the function
`getDeviceFromBackingFile` could be a little bit slower.
