bootmem: Move __alloc_memory_core_early() to nobootmem.c

Now that bootmem.c and nobootmem.c are separate, there's no reason to
define __alloc_memory_core_early(), which is used only by nobootmem,
inside #ifdef in page_alloc.c.  Move it to nobootmem.c and make it
static.

This patch doesn't introduce any behavior change.
