s390/nmi: Annotate s390_handle_damage() with __noreturn
s390_handle_damage() ends by calling the non-returning function
disabled_wait() and therefore also never returns. Annotate it with the
__noreturn compiler attribute to improve compiler optimizations.
Remove the unreachable infinite while loop.
