numa: postpone options post-processing till machine_run_board_init()

in preparation for numa options to being handled via QMP before
machine_run_board_init(), move final numa configuration checks
and processing to machine_run_board_init() so it could take into
account both CLI (via parse_numa_opts()) and QMP input
