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.
