Subject: x86: Replace memblock_x86_find_in_range_size() with
 for_each_free_mem_range()

setup_bios_corruption_check() and memtest do_one_pass() open code
memblock free area iteration using memblock_x86_find_in_range_size().
Convert them to use for_each_free_mem_range() instead.

This leaves memblock_x86_find_in_range_size() and
memblock_x86_check_reserved_size() unused.  Kill them.
