memblock: replace usage of __memblock_free_early() with memblock_free()

memblock: replace usage of __memblock_free_early() with memblock_free()

__memblock_free_early() is only used by the convenience wrappers, so
essentially we wrap a call to memblock_free() twice.  Replace calls of
__memblock_free_early() with calls to memblock_free() and drop the former.
