Peter Oberparleiter dc31841fcd s390/chsc: Add exception handler for CHSC instruction 
commit 7775913724 upstream.

Prevent kernel crashes due to unhandled exceptions raised by the CHSC
instruction which may for example be triggered by invalid ioctl data.

Fixes: 64150adf89 ("s390/cio: Introduce generic synchronous CHSC IOCTL")
