s390x/css: handle format-0 TIC CCW correctly
For TIC CCW, bit positions 8-32 of the format-1 CCW must contain zeros;
otherwise, a program-check condition is generated. For format-0 TIC CCWs,
bits 32-63 are ignored.
To convert TIC from format-0 CCW to format-1 CCW correctly, let's clear
bits 8-32 to guarantee compatibility.
