    Allow Partition > New on unallocated whole disk devices again (#788308)
    
    Fix up following switch from whole_device flag to TYPE_UNPARTITIONED.
    
    Again use FS_UNALLOCATED to determine if a partition represents
    unallocated space and creation of a new partition should be allowed.
    This is so that trying to create a new partition on a whole disk device
    shows the "No partition table found on device /dev/DEV" warning again.
    
    Bug 788308 - Remove whole_device partition flag
