mm: remove unnecessary empty range check in early_calculate_totalpages()

Browse source

early_calculate_totalpages() iterates the memory ranges with
for_each_mem_pfn_range() and calls node_set_state(nid, N_MEMORY) only when
end_pfn - start_pfn is non-zero. for_each_mem_pfn_range() never returns an
empty range, so start_pfn < end_pfn always.

Therefore the check is unnecessary, so remove it.

No functional change.
