Peter Oberparleiter e8fca95592 zdev: Fix off-by one errors in cio_ignore handling ...

chzdev fails to generate correct cio_ignore udev-rules for a CCW device
with device number 0xffff. Also chzdev aborts due to a segmentation
fault when a CCW device with CSSID 0xff is configured. Both issues are
caused by off-by-one errors while interpreting CCW device ID limits
CSSID_MAX, SSID_MAX and DEVNO_MAX.

Fix these errors by correctly interpreting CCW device ID limits.
