powerpc/64s: Fix build failures with CONFIG_NMI_IPI=n
I broke the build when CONFIG_NMI_IPI=n with my recent commit to add
arch_trigger_cpumask_backtrace(), eg:
stacktrace.c:(.text+0x1b0): undefined reference to `.smp_send_safe_nmi_ipi'
We should rework the CONFIG symbols here in future to avoid these
double barrelled ifdefs but for now they fix the build.
