s390/mm: ensure switch_mm() is executed with interrupts disabled

Architecture callback switch_mm() is allowed to be called with

does not expect that. Let's follow other architectures and make
sure switch_mm() is always executed with interrupts disabled,
regardless of what happens with the generic kernel code in the
future.
