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.
