qemu: block: Make 'slice' layer effective for 'raw' storage source

Browse Source 
Rather than pulling the configuration of the storage slice into the
'format' layer make the 'slice' layer effective for raw disks with a
storage slice. This was made possible by the recent refactors which made
the 'format' layer optional if not needed.
