[PATCH v2 8/8] mm/hugetlb: remove unnecessary empty range check in hugetlb_bootmem_set_nodes()

[Sang-Heon Jeon]

hugetlb_bootmem_set_nodes() iterates the memory ranges with
for_each_mem_pfn_range() and calls node_set(nid, hugetlb_bootmem_nodes)
only when end_pfn > start_pfn. 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.
