x86: Use absent_pages_in_range() instead of memblock_x86_hole_size()
memblock_x86_hole_size() calculates the total size of holes in a given range according to memblock and is used by numa emulation code and numa_meminfo_cover_memory(). Since conversion to MEMBLOCK_NODE_MAP, absent_pages_in_range() also uses memblock and gives the same result. This patch replaces memblock_x86_hole_size() uses with absent_pages_in_range(). After the conversion the x86 function doesn't have any user left and is killed.
