mm/nobootmem.c: add return value check in __alloc_memory_core_early()
When memblock_reserve() fails because memblock.reserved.regions cannot
be resized, the caller (e.g. alloc_bootmem()) is not informed of the
failed allocation. Therefore alloc_bootmem() silently returns the same
pointer again and again.
This patch adds a check for the return value of memblock_reserve() in
__alloc_memory_core().
