s390/sclp_vt220: fix console name to match device
[ Upstream commit b7d91d230a119fdcc334d10c9889ce9c5e15118b ]
Console name reported in /proc/consoles:
ttyS1 -W- (EC p ) 4:65
does not match the char device name:
crw--w---- 1 root root 4, 65 May 17 12:18 /dev/ttysclp0
so debian-installer inside a QEMU s390x instance gets confused and fails
to start with the following error:
steal-ctty: No such file or directory
