bootmem: Reimplement __absent_pages_in_range() using for_each_mem_pfn_range()

Browse source

__absent_pages_in_range() was needlessly complex.  Reimplement it
using for_each_mem_pfn_range().

Also, update zone_absent_pages_in_node() such that it doesn't call
__absent_pages_in_range() with @zone_start_pfn which is larger than
@zone_end_pfn.
