memblock: remove return value of memblock_free_all() 

memblock_free_all() returns the total count of freed pages and its callers
 used this value to update totalram_pages. This update is now anyway a part
 of memblock_free_all() and its callers no longer check the return value, so
 make memblock_free_all() void.
