powerpc: Fix default_machine_crash_shutdown #ifdef botch

paulmck · ozbenh · commit c2be05481f61 · 2010-07-08T18:11:45.000+10:00
crash_kexec_wait_realmode() is defined only if CONFIG_PPC_STD_MMU_64
and CONFIG_SMP, but is called if CONFIG_PPC_STD_MMU_64 even if !CONFIG_SMP.
Fix the conditional compilation around the invocation.
