    don't segfault on a device-mapper device with no target
    
    * libparted/arch/linux.c (_dm_maptype): Don't dereference NULL
    for a device-mapper device with no target.  Use the string
    "NO-TARGET" instead.  Reported by Mike Hwang in
    http://thread.gmane.org/gmane.comp.gnu.parted.devel/2432
