powerpc/smp: Adjust nr_cpu_ids to cover all threads of a core

Browse source

[ Upstream commit 5580e96dad ]

If nr_cpu_ids is too low to include at least all the threads of a single
core adjust nr_cpu_ids upwards. This avoids triggering odd bugs in code
that assumes all threads of a core are available.
