arch/x86: Fix payload loading via bounce-buffer
Fix regression (supposedly) after commit:
23d62dd lib/bootmem: Add more bootmem tags
Without RELOCATABLE_RAMSTAGE, payload is allowed to overwrite
memory regions of the running ramstage. This case is handled
gracefully via a bounce-buffer implementation in arch/x86/boot.c.
