Heiko Carstens 0cd9b7230c s390: add separate program check exit path 
System call and program check handler both use the system call exit
path when returning to previous context. However the program check
handler jumps right to the end of the system call exit path if the
previous context is kernel context.

This lead to the quite odd double disabling of interrupts in the
system call exit path introduced with commit ce9dfafe29be ("s390:
fix system call exit path").

To avoid that have a separate program check handler exit path if the
previous context is kernel context.
