x86: don't clear nodes_states[N_NORMAL_MEMORY] when numa is not compiled in

Alex found that specjbb2005 still can not run with hugepages on an
x86-64 machine.  This only happens when numa is not compiled in.

The root cause: node_set_state will not set it back for us in that case,
so don't clear that when numa is not select in config

[ v2: use node_clear_state instead ]
