[IA64] Bugfix for system with 32 cpus
On a system where there are no hot pluggable cpus "additional_cpus"
is still set to -1 at the point where we call per_cpu_scan_finalize().
If we didn't find an SRAT table and so pick the default "32" for the
number of cpus, when we get to:
high_cpu = min(high_cpu + reserve_cpus, NR_CPUS);
we will end up initializing for just 31 cpus ... and so we will
die horribly when bringing up cpu#32.
Problem introduced by: 2c6e6db41f01b6b4eb98809350827c9678996698
"Minimize per_cpu reservations."
