mm/mm_init.c: only align start of ZONE_MOVABLE on nodes with memory

Browse Source 
At the beginning of find_zone_movable_pfns_for_nodes(), it has properly
set node_states[N_MEMORY] in early_calculate_totalpages().

Instead of iterating over all possible nodes, we can just do the alignment
on nodes with memory.
