x86/numa_emulation: Recalculate numa_nodes_parsed from emulated nodes

When emulating NUMA, the kernel's emulated NUMA configuration may contain
more or less nodes than there are physical nodes.

In numa_emulation(), we recalculate numa_meminfo/numa_distance/__apicid_to_node
according to the number of emulated nodes, except numa_nodes_parsed, which is
arguably an omission.

Recalculate numa_nodes_parsed as well.
