x86: improve UP kernel when CPU-hotplug and SMP is enabled
commit 649c6653fa94ec8f3ea32b19c97b790ec4e8e4ac upstream
num_possible_cpus() can be > 1 when disabled CPUs have been accounted.
Disabled CPUs are not in the cpu_present_map, so we can use
num_present_cpus() as a safe indicator to switch to UP alternatives.
