Actually using disk PrlVmDev_GetFriendlyName as id on
detaching volumes is not a problem. We can only detach
hard disks and these can not have empty friendly names.
But upcoming update device functionality for cdroms
can not use disk source as id at all as update operation
typically change this same source value. Thus we will need
to use cdrom bus and cdrom target name as cdrom id. So in attempt
to use same id scheme for all purpuses lets fix hard disk
detach function to use new id.
