s390/syscall: Use enter_from_user_mode_randomize_stack()
enter_from_user_mode_randomize_stack() replaces enter_from_user_mode() and
the subsequent invocation of add_random_kstack_offset_irqsoff().
As a bonus this avoids the overhead of get/put_cpu_var() in
add_random_kstack_offset().
No functional change.
