    Display unrecognised whole disk devices as all grey again (#788308)
    
    Following the switch from whole_device flag to TYPE_UNPARTITIONED,
    unallocated space can be found in two partition types:
        TYPE_UNALLOCATED
        TYPE_UNPARTITIONED  (only when filesystem == FS_UNALLOCATED)
    
    As the file system in both cases is FS_UNALLOCATED check for that when
    determining whether a partition is unallocated or not.
    
    Bug 788308 - Remove whole_device partition flag
