s390/process: Fix kernel thread function pointer type

Browse Source 
[ Upstream commit d0478f5d3c ]

In case of a kernel thread __ret_from_fork() calls the specified function
indirectly. Fix the kernel thread function pointer, since kernel threads
return an int instead of void.

Fixes: 56e62a7370 ("s390: convert to generic entry")
