x86-32, NUMA: use sparse_memory_present_with_active_regions()
Instead of calling memory_present() for each region from NUMA init, call sparse_memory_present_with_active_regions() from paging_init() similarly to x86-64. For flat and numaq, this results in exactly the same memory_present() calls. For srat, if there are multiple memory chunks for a node, after this change, memory_present() will be called separately for each chunk instead of being called once to encompass the whole range, which doesn't cause any harm and actually is the better behavior.
