memblock: fix crash when reserved memory is not added to memory
After commit 61167ad5fecd ("mm: pass nid to reserve_bootmem_region()") nid of a reserved region is used by init_reserved_page() (with CONFIG_DEFERRED_STRUCT_PAGE_INIT=y) to access node strucure. In many cases the nid of the reserved memory is not set and this causes a crash. When the nid of a reserved region is not set, fall back to early_pfn_to_nid(), so that nid of the first_online_node will be passed to init_reserved_page().
