powerpc: Fix build for 32-bit SMP configs
attr_smt_snooze_delay is only defined for CONFIG_PPC64, so protect the attribute removal with the same condition. This fixes this build error on 32-bit SMP configurations: /data/home/miltonm/next.git/arch/powerpc/kernel/sysfs.c: In function ‘unregister_cpu_online’: /data/home/miltonm/next.git/arch/powerpc/kernel/sysfs.c:722: error: ‘attr_smt_snooze_delay’ undeclared (first use in this function) /data/home/miltonm/next.git/arch/powerpc/kernel/sysfs.c:722: error: (Each undeclared identifier is reported only once /data/home/miltonm/next.git/arch/powerpc/kernel/sysfs.c:722: error: for each function it appears in.)
