partitions: fix sometimes unreadable partition strings
Fix this garbage happening quite often: ==> sda: scsi 3:0:0:0: CD-ROM TOSHIBA ==> sda1 sda2 sda3 sda4 <sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray ^^^ Uniform CD-ROM driver Revision: 3.20 sr 3:0:0:0: Attached scsi CD-ROM sr0 ==> sda5 sda6 sda7 > Make "sda: sda1 ..." lines actually lines.
