topology: alternate fix for ia64 tiger_defconfig build breakage
Define stubs for the numa_*_id() generic percpu related functions for
non-NUMA configurations in <asm-generic/topology.h> where the other
non-numa stubs live.
Fixes ia64 !NUMA build breakage -- e.g., tiger_defconfig
Back out now unneeded '#ifndef CONFIG_NUMA' guards from ia64 smpboot.c
