memblock: fix crash when reserved memory is not added to memory (2024-01-19 10:53:59 +0200)

----------------------------------------------------------------
memblock: fix crash when reserved memory is not added to memory

When CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled, the initialization of
reserved pages may cause access of NODE_DATA() with invalid nid and crash.

Add a fall back to early_pfn_to_nid() in memmap_init_reserved_pages() to
ensure a valid node id is always passed to init_reserved_page().
