hw/i386/acpi-build: Get NUMA information from struct NumaState

Browse Source 
Since commits aa57020774 ("numa: move numa global variable
nb_numa_nodes into MachineState") and 7e721e7b10 ("numa: move
numa global variable numa_info into MachineState"), we can get
NUMA information completely from MachineState::numa_state.

Remove PCMachineState::numa_nodes and PCMachineState::node_mem,
since they are just copied from MachineState::numa_state.
