Stefan Liebler 76aaa13d5d S390: Remove not needed stack frame in syscall function.
As an svc invocation does not clobber any user space registers
despite of the return value r2 and it does not need a special
stack frame. This patch gets rid of the extra frame.
We just have to save and restore r6 and r7 as those are
preserved across function calls.
