mm/page_alloc: fix the range check for backward merging
The current check for 'backward merging' within add_active_range() does not seem correct. start_pfn must be compared against early_node_map[i].start_pfn (and NOT against .end_pfn) to find out whether the new region is backward-mergeable with the existing range.
