node_states_clear has the following if statements:
if ((N_MEMORY != N_NORMAL_MEMORY) &&
(arg->status_change_nid_high >= 0))
...
if ((N_MEMORY != N_HIGH_MEMORY) &&
(arg->status_change_nid >= 0))
...
N_MEMORY can never be equal to neither N_NORMAL_MEMORY nor
N_HIGH_MEMORY.
Similar problem was found in [1].
Since this is wrong, let us get rid of it.
