memblock, x86: Make free_all_memory_core_early() explicitly free lowmem only
nomemblock is currently used only by x86 and on x86_32
free_all_memory_core_early() silently freed only the low mem because
get_free_all_memory_range() in arch/x86/mm/memblock.c implicitly
limited range to max_low_pfn.
Rename free_all_memory_core_early() to free_low_memory_core_early()
and make it call __get_free_all_memory_range() and limit the range to
max_low_pfn explicitly. This makes things clearer and also is
consistent with the bootmem behavior.
This leaves get_free_all_memory_range() without any user. Kill it.
