I missed to set the CC in the CHSC instruction when I refactored
the CC setting in the IO instructions with the following commit:
	s390/ioinst: Moved the CC setting to the IO instruction handlers
This patch now restores the correct behaviour of CHSC by setting the
condition code 0 at the end of the instruction.
