mm: memblock: remove return value of memblock_free_all()
No one checks the return value of memblock_free_all().
Make the return value void.
memblock_free_all() is used on mem_init() for each
architecture, and the total count of freed pages will be added
to _totalram_pages variable by calling totalram_pages_add().
so do not need to return total count of freed pages.
