    Fix false busy detection of unusual case with Linux Software RAID (#712533)
    
    In this unusual setup of having one Linux Software RAID array
    partitioned and a second array not partitioned, /dev/md1p1 partition in
    the first array is falsely reported as busy when the file system filling
    the second array /dev/md2 is mounted.
    
      Partition   RAID                File System        Mount mount
      ---------   -----------------   ----------------   -----------
      /dev/sdb1   SWRAID /dev/md1
                         /dev/md1p1   ext4,Label=test1   (Unmounted)
      /dev/sdb2   SWRAID /dev/md2     ext4,Label=test2   /mnt/2
    
    This again affects Debian 6, Debian 7 and RHEL/CentOS 6.x and is as a
    result of the this bug fixed in libparted 2.4:
        http://git.savannah.gnu.org/cgit/parted.git/commit/?id=db52898c214310dab4ed84e6cb2f9ffc8c3aa502
        linux: also detect "in-use" dmraid and scsi-Nth (N>=16) partition
    
    Fix by not using libparted's ped_partition_is_busy() to determine if a
    normal or logical partition is busy.
    
    Bug #712533 - Partitions not detected as busy inside Software RAID on
                  some distros
