Alexey Dobriyan 9c867fbe06 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.
