[S390] Fix compile error on 31bit without preemption

Browse Source 
Commit b8e7a54cd06b0b0174029ef3a7f5a1415a2c28f2 introduced a compile
error if CONFIG_PREEMPT is not set:

arch/s390/kernel/built-in.o: In function `cleanup_io_leave_insn':
/space/kvm/arch/s390/kernel/entry.S:(.text+0xbfce): undefined reference to `preempt_schedule_irq'

This patch hides preempt_schedule_irq if CONFIG_PREEMPT is not set.
