I think the volume+disk is redundant. Maybe simply allocate_image or
allocate_volume?

Thinking about this, are there any cases where we do not want to have
the checks done first? I.e. can we simply add the checks as part of
vdisk_alloc itself (would require passing along the content type for the
checks but would avoid the need for this helper)?
